Perfect combination, this is the process of billet heating furnace!
At present, in the steel industry, domestic and foreign manufacturers have adopted the continuous casting technology of billet heating furnace. After the caster billet, the billet surface temperature dropped to about 800 degrees. But the center temperature is about 1050 degrees. As the billet surface temperature is low, it can not be directly rolled. The user sends the billet to the semi-finished product shop for processing or to the holding furnace. The average billet temperature is 925 degrees. If you increase the surface temperature inline, the temperature will be increased from 925 degrees to 1250 degrees. Then we can use the rolling mill to roll.
Billet surface temperature is lower, the center temperature is higher. Induction heating is a method that first heats the surface to the inside. Therefore, making full use of billet induction furnace to improve the billet surface heat is the best way to save energy. Making full use of billet residual heat, foreign steel mills have achieved this process. Heating from 925 to 1250 ° C requires 45kw/h per ton power consumption. If the heating efficiency is 70%, the power consumption is 65kw/h per ton.
Continuous billet heating furnace features:
1.Induction billet heater: billet heating furnace is divided into preheating section, heating section and holding section. The rollers between induction heaters is made of 304 stainless steel and cooled by water.
2.Lining: long-life design, durable, large refractory cement.
3.Heating method: induction heating technology, internal heat generated billet. without warm-up time, the user can start the entire billet heating furnace in a short time.
4.With 12 pulse power supply and special custom transformers, less harmonic pollution.
Continuous billet heating furnace routine maintenance:
1.Frequently clean the dust inside the power distribution cabinet, set up a special room for the inverter device, we must always pay attention to cleaning work to prevent insulation failure.
2.The regular inspection and maintenance for the power supply.
Regularly check the fastening bolts, nuts, connectors and other parts.
Regularly check the voltage and current to prevent failure.
3.Frequently check the load connection is intact, the insulation is reliable.
