Understand precision steel casting work

The production field is in full swing, and multiple sections are linked. Vertical lathe, gantry milling machine, vertical milling machine and other equipment has been installed, the site machine roar, sparks splashed, workers are busy for customers to rush to make cylinder, valve housing, steam room, precision casting steel parts and other parts products. At the same time, the 6-meter diameter vertical car is undergoing final commissioning and installation.

The worker is making molds.

The reporter saw in the first phase of the company's factory that the entire workshop was divided into several production workshops, and the workers were completing many processes such as mold making, molten steel pouring, and original product billets according to the prescribed division of labor. When Fan Caiyong, general manager of the company, entered the workshop for an interview, the reporter personally felt the bursts of heat from the hot steel and realized the fiery production scene.

However, in the second batch of plants that are about to be completed, the reporter saw that some equipment has been installed and put into production, and the original billet that was originally "gray and white" has achieved "transformation" after secondary polishing and finishing.

The workers polished the raw blanks.

This is my company spent a lot of money to build the finishing production workshop, next year will be fully put into production. Fan Caiyong pointed to a table of precision instruments told reporters that after the completion of all projects, Jinlei Heavy Industry will have CNC milling machines, CNC lathes, CNC boring machines, precision grinding machines and other processing equipment, can carry out large, medium and hard metal parts production and processing, so that the company's products include from the original blank to the finished product processing, forming a complete product line.

Focus on products:

Order production, committed to specialized production.

The reporter saw a huge chain in the company's factory building, which moved slowly with the crane and was transported to the next process for polishing.

"The chain produced by our company for SIMCO, Australia, is specially made for large mining machinery and weighs 146 kilograms in just one circle.

Creating huge chains.

In recent years, the company has the courage to overcome the adverse effects of economic depression at home and abroad, and has signed many orders at home and abroad by using its own technology. Not only signed a series of orders with domestic Dongfang Turbine Co., LTD., Chongqing Pump Factory, CSSC Construction and other enterprises, and actively explore overseas, and successfully signed contracts with Italy Danieli, PSP company, Australia SIMCO Company, APCO, K2 company and other companies. In 2020, the company ordered about 477 tons of orders from overseas customers, with a total sales of 7.5 million yuan.

In order to improve the quality of the company's products, the company actively research and develop new technologies to improve production efficiency. Specifically, in 2019, the company promoted the smelting and the use of slip in the LF refining furnace of super-large castings to normalize the success rate of super-large castings to 100% through actual adjustments; Optimize slag washing and wire feeding furnace refining process, improve the company's smelting level, improve product quality; Improve the surface sand process, greatly reduce the sand and porosity defects, improve the cleaning and cutting efficiency...
