Good products need solid technology
As a modern high-tech enterprise, it is difficult to have long-term development without solid technical support.
“Only with solid technology can we make good products.”Xiang Renfa said that for a drill that seems to be just a lump of iron, its raw materials and processing technology are the key, which guarantees the leading position of the product in the industry..
The raw materials used in the “Super King Kong” brand rock drill bits are worth 1.80,000 yuan a ton of steel is about four times that of ordinary steel. The steel contains rare metals such as nickel and chromium. Various metals are smelted into special steels according to a certain ratio, and this “proportion table” is mastered in Sangrenfa’s hands.The drill bit also contains cemented carbide, such as tungsten carbide, cobalt, etc. The price of a cemented carbide is 50 yuan.
“The other is heat treatment technology.”Sang Renfa pointed to the boilers inlaid underground in the production workshop. After forging, the drill bit needs to be heated to change the properties of the steel to maximize its performance. Temperature and duration are the key points. , Once the operation is wrong, the performance of the drill will be greatly reduced.The operating instruments connected to the boiler have strict monitoring of the temperature and time of the heat treatment process.
At present, Super King Kong Machinery has more than 70 types of drill bits and down-the-hole impactors..Including positive circulation down-the-hole impactor; reverse circulation impactor; various forward and reverse circulation down-the-hole drill bits, etc., as well as eccentric tube-following drilling tools and centering tube-following drilling tools used in overburden and loose rock formations , Slider type tube-following tool, double tube-following tool and other rig accessories.
These products can be widely used in earth and stone engineering, mining, water well engineering and construction engineering, geothermal drilling, municipal engineering and other fields.
Production workers are processing the rock drill bit
Products are generally recognized by the international market
Xiang Renfa, who has more than ten years of experience in the industry, knows the importance of product quality and technology.
Recall that many years ago, the fracture rate of domestic rock drill bits was relatively high, even reaching 40%.”Once the drill bit breaks, it is easy to mix into the rock pile and difficult to find, and the drill bit and the stone fall into the rock crusher, which can easily damage the machine worth hundreds of millions of yuan..”Sang Renfa said that when foreign customers heard that they were made in China, they were determined not to use them, and even the free trial was rejected..
In the original company, Xiang Renfa and his colleagues worked hard to make the fracture rate of the rock drill bit lower than 1%, and the international market gradually accepted and used it..
Behind the success of R&D are several failures and huge amounts of funds..According to Xiang Renfa, because of the high cost of special steel, once the raw material smelting process and manufacturing process have problems, all the products worth 5 million yuan will be burned, and they have to start all over again..
“Now the intact rate of the rock drill bits produced by our Super King Kong has reached 99.5%, the quality is very stable.”Sang Renfa revealed that more than half of the company’s products are exported to Asia, Europe, South America, Oceania, Africa and other five continents, and have been well received by customers. The market scope will be further expanded in the future..
On the basis of existing technology, Chaojingang Machinery has continuously increased investment in research and development, and jointly developed new products and new technologies with universities.In June of this year, we jointly carried out the research and development of the project “Optimization Design of RC High Pressure Reverse Circulation Impactor Gas Field Flow Channel” with Changsha University.
In the future, Chaojingang Machinery will also strengthen cooperation with universities and create conditions for the upgrading and innovation of enterprise products with the help of university R&D teams, modern laboratories and testing equipment..
Rock drilling equipment to be exported
Broad prospects for future development of rock drilling equipment
Although he has just started his business, with his grasp and analysis of the market prospects, Xiang Renfa has firm confidence.
“Our CT55A-138 drill bit is priced at 1,600 yuan each, and the service life is about two days..”Sang Renfa picked up a rock drill bit and introduced that each drill bit has a limited service life. The average rock drill length is between 400 and 500 meters. A new bit must be replaced.” As a consumable product, rock drilling The drill bit has a faster replacement speed.”
The demand in the global market is also great.According to Xiang Renfa, an internationally renowned manufacturer of machinery products has annual sales of 6 billion US dollars in its drill products business, while China’s annual sales are less than 2 billion US dollars..
Xiang Renfa analyzed that the demand for rock drilling equipment in the domestic market is increasing, and there are more and more application fields..”For example, drilling a water well requires the use of rock drilling equipment and drill bits.Nowadays, not only do wells stay in the north, but the south is gradually increasing..”In addition to drilling water wells, the market expansion in geothermal, photovoltaic and other fields also has a huge demand for rock drill bits..
“Some highways never freeze, this also applies geothermal technology.”Sang Renfa said that the correlation between industry sectors will also bring new business opportunities to rock drilling equipment..
While setting foot in the rock drilling series products, Super King Kong Machinery has also entered the field of remanufacturing.”In order to avoid waste, we will also recycle the rock drill bits and return them to the furnace for re-forging..”Sang Renfa said that after the end of the service life of each rock drill bit, the internal alloy can still be used, and they will buy back the product from the customer for a certain amount..
In the next step, Chaojingang Machinery will strengthen the construction of the R&D center, and the configuration of personnel and equipment, establish an enterprise technology center, establish a raw material R&D team, strengthen the R&D team, and lay the foundation for the rapid development of the company.
Entrepreneurship impression gives up one million annual salary and wants to give yourself a chance
“Since I founded the company, I have been haggard a lot. I don’t think I can see that I am 36 years old..”Sang Renfa said while visiting the production workshop with reporters..
After graduating from university in 2005, Xiang Renfa successfully entered the job corresponding to his profession. He spent 13 years from the initial technicians to professionals with rich R&D experience in the industry..During this period, the project led by him has applied for 25 patents and won 2 provincial achievement awards and 2 Changsha Science and Technology Progress Awards..
Considering his actual and future development, Xiang Renfa decided to start his own business and established Changsha Chaojingang Machinery Manufacturing Co., Ltd. in August 2017 and settled the company in Liuyang High-tech Zone.
“I just think I’m still young and want to give myself a chance. I didn’t make this decision for a while..”Talking about the initial decision, Sang Infa felt a little bit touched..Family members don’t agree with him that he is going to start a business. They think that he gave up a million annual salary, but chose to start a difficult business. This is just tossing..Sang Renfa thinks that this will be a new exploration, anyway you have to try it.
“There are no good workers, only good partners.”This line of the movie even expressed the heartfelt voice of Xiangren. He invited his companions to invest in shares. 12 professional and technical talents laid the foundation for the company’s R&D team..”Because of their participation and teamwork, it has avoided fighting alone and made many difficult problems a breeze..”
Xiang Renfa said that entrepreneurship is very risky. Almost all of the assets he has accumulated over the past 10 years are in it, and he is facing failure at any time, and there is a possibility of “returning to the pre-liberation period”..
“I don’t know that firewood, rice, oil, and salt are expensive.If you don’t start a business, you can’t feel the pain of starting a business. It’s really hard. I have the idea of giving up several times..”Sang Renfa said that he used to be a senior executive in a company, with a decent salary and a high salary, and his job is much easier than it is now..But despite this, Xiang Renfa still firmly believes in starting a business, especially seeing that his company is gradually growing and the products are gradually being recognized by the market, and he feels that everything is worth it..
“I lost more than 20 catties in one year after starting my business, and I got very tan.”Sangren laughed and rolled up his short sleeves. The white skin under the sleeves and the black and red roughness of his arms formed a clear contrast..Now he has a lot of things to communicate and deal with every day, except for sleeping, he is working, but Xiang Renfa is still “deeply trapped”, feeling every sense of accomplishment that entrepreneurship brings him..
