Complete stroke thermal insulating cover for continuous casting conveying roller way

Abstract

The present invention provides an omnirange heat-insulating cover for continuous casting roll gang. It is formed from several heat-insulating cover bodies. In the whole roll gang, including casting billet cutting zone roll gang, dummy bar roll gang and dressing machine roll gang, over every roll gang a heat-insulating cover body which can be opened is set respectively. The heat-insulating cover body positioned over the casting billet cutting zone roll gang is made into drawing-pulling type structure, the heat-insulating cover body positioned over the dummy bar roll gang is a tilting structure, formed from several heat-insulating cover bodies, at one side of every heat-insulating cover body its respective tilting mechanism is mounted; and the heat-insulating cover body positioned over the dressing machine is a translational structure, the transverse beam in the top portion of heat-insulating cover body can make the several cover bodies be connected into one body, and two ends of said transverse beam are respectively slide-connected with two transversely-moved guideways by means of pulleys.

Description

technical field [0001] The invention belongs to the continuous casting technology, in particular to a thermal insulation device for a continuous casting conveying roller table. Background technique [0002] During the conveying process of the continuous casting slab, no heat preservation measures are used, and the temperature drop of the slab is very large, especially in the conveying roller table of the slab cutting area. During the cutting process of about 10 meters, the surface temperature drop of the slab is as high as 70°C Around, during the entire roller table conveying process, the surface temperature drop of the billet is as high as about 150°C, which reduces the temperature of the billet entering the heating furnace, resulting in a huge waste of energy, seriously restricting the productivity of the rolling mill, and also reducing the use of the billet. Performance is greatly reduced. Although the heat preservation cover technology has been reported for a long time,...

Problems solved by technology

[0002] During the conveying process of the continuous casting slab, no heat preservation measures are adopted, and the temperature drop of the slab is very large, especially in the conveying roller table of the slab cutting area. Around, during the entire roller table conveying process, the surface temperature drop of the billet is as high as about 150°C, which reduces the temperature of the billet entering the heating furnace, resulting in a huge waste of energy, seriously restricting the productivity of the rolling mill, and also reducing the use of the billet. greatly reduced performance

Although the heat preservation cover technology has been reported for a long time, it can truly realize the whole process of heat preservation of the continuous casting conveying roller table, especially the heat preservation of the conveying roller table in the billet cutting area, and no relevant technology has been disclosed.

In addition, during the cutting process, sparks radiate and high-temperature slabs also increase many unsafe factors, which affect the on-site environment
