In June, Dalian Special Steel Co., Ltd. contracted 3,355 tons of materials, an increase of 236 tons on the basis of a record last month. Moreover, before the first trial system, the 30CrNiMo8 variety was produced by Beiman Special Steel. At present, the contract quantity of Dalian Special Steel Company's products has been continuously increased on the basis of stable production. This month, there are 25 specifications of 65-250mm, which have been put into storage as of the end of June. 339 tons.

In June, Dalian Special Steel Quenching and Tempering Line received a contract of 4,618.214 tons, which exceeded the current production capacity, the production cycle was tight, and the span of the group was large. The initial scheduling of the month was fully considered to adjust the specifications of the material, and the distance between the units was prioritized. Strictly control the progress and surface quality of the process blanks in production, timely straighten the curved billets, and repair the surface crack blanks in time to improve the quenching and tempering efficiency. The daily average quenching and tempering plan is 40 tons of small quenching furnace and 70 tons of large quenching furnace; In terms of the cracking of the quenched material and the unstable temperature of the heating, the quality of the quenched material is improved by optimizing and improving the process; the equipment is strengthened by timely system maintenance and key points to ensure continuous production of the quenching furnace. Through the above measures, the production of quenched and tempered materials has once again set a new delivery record since the start of production.
