Further heat storage is filled in the heat-storage type burner.Heat storage type combustion exhaust gas temperature is low, exhaust gas heat loss
Lose small, the thermal efficiency of equipment greatly improves, and reduces fuel consumption.
Further the roller both sides on the roller-way are provided with rib.There is provided ribs to have guiding role for roller,
Continuous casting billet sideslip and deflection are reduced, improves the lumber recovery of continuous casting billet.
Further the upper insulation cover, lower insulation cover shell are steel cage shell, and internal layer is insulating layer, and insulating layer is resistance to pour into a mould
Fire material and refractory fibre.
Further the heat accumulating type heating unit is corresponding according to roller-way length situation every 0.5 ~ 1.5 meter of one group of setting
Adjust quantity.
Further the lower insulation cover is equipped with slag door.The oxide that continuous casting billet is fallen in conveying is contributed to concentrate
On the lower smaller section in insulation cover bottom, open slag door and collect oxide, it is easy to operation.
Advantageous effect:Compared with prior art, the utility model has the advantage of:
1)The online concurrent heating on the roller-way of continuous casting zone or continuous casting to milling train makes the full base temperature of continuous casting billet meet rolling and wants
It asks, it is energy saving, substantially reduce the cost using heating stove heat;
2)Without heating furnace reheating, simplify the production procedure between continuous casting and steel rolling, realize the continuous casting of continuous casting billet
Tandem rolling;
3)It is energy saving using Regenerative Combustion Technology;
4)Heat patching device minimizes, and substantially reduces investment and the operating cost of heating equipment;
