1. The roll sleeve of the roll forming machine is sprayed with 1/4 concentration of anti-oxidation and decarburization medium before tempering and quenching to reduce decarburization and oxidation of the roll sleeve surface, improve material utilization, and reduce decarburization-induced roll cracking factors.
2. Before the steel billet is loaded into the furnace, spray anti-oxidation medium to reduce the oxidation and decarburization layer of the steel billet; in the dephosphorization process, high cooling rate medium is used to maintain the water pressure to strengthen the dephosphorization effect, thereby reducing the wear of the roll caused by the scale.
3. It is best to use fast cooling medium for the entire rolling mill, which can reduce the working temperature of the roll by more than 50 degrees and prolong the service life. At the same time, the steel produced can be guaranteed to be rust-free for 3 to 6 months, and the rolling equipment can also be effectively protected. It is no longer necessary to replace the waste water, reducing the manufacturer's use cost and sewage discharge cost.
4. Carry out several experiments on the project to ensure the stable quality of the produced composite rolls and ensure that the service life of the composite rolls produced by new technology is increased to more than 3 times.
