China heavy steam group Ji'nan bridge box Co., Ltd.
Customer introduction: One of the largest manufacturers of heavy truck bridges in China, specializing in matching the leading enterprises of heavy truck industry in China. It also serves other vehicle and parts businesses in the automotive industry. Production of front axle, front drive axle and wheel deceleration drive axle and clutch assembly and other products.
State of use: with different types of industrial furnace equipment, the initial use of the German brand quenching medium, the high hardness of the product core (technical requirements HRC33-48, the actual value of the upper limit of HRC45-48), the product deformation qualification rate has not been improved.
State of use: with different types of industrial furnace equipment, the initial use of the German brand quenching medium, the high hardness of the product core (technical requirements HRC33-48, the actual value of the upper limit of HRC45-48), the product deformation qualification rate has not been improved.
Solution: Kerun joint enterprise production, quality, procurement and other departments, after the pre - Communication and research, choose the multi - purpose furnace equipment in this enterprise, use KR-228C (wheel special quenching oil). Test for nearly three months, 50 redundant stove products such as steering knuckle pin and AC16 input shaft were tested. At the same time, compared with the processed products of German brand, taking STR passive cone gear as an example, the microstructure of products is M2-4 grade, and the hardness of core is stable between HRC40-45.

Effect evaluation: Kerun has lasted nearly ten years of service, The qualified rate of the deformation of the production pieces is up to 97.3%, compared with foreign brands of quenching medium increased by 2 percentage points. At the same time, the enterprise has advanced level of friction machine, processing center cluster, hot die forging press production line and so on, including machine processing, quenching medium supporting equipment, the overall solution is being used gradually.
