Heat insulation rail weighbridge for molten iron weighing and laying method thereof

Abstract

The invention discloses a heat insulation rail weighbridge for molten iron weighing and a laying method thereof, and belongs to the technical field of ferrous metallurgy high-temperature hot melting weighing. The heat insulation rail weighbridge for molten iron weighing comprises a weighing platform, supporting platforms and foundation walls. The supporting platforms are arranged at the two sidesof the weighing platform respectively, the foundation walls are arranged at the two ends of the weighing platform respectively, and the weighing platform is hermetically and flexibly connected with the supporting platforms and the foundation walls. The weighing platform and the supporting platforms are respectively provided with a thermal insulation layer and a heat-resisting layer, and a plurality of segmentation parts are uniformly distributed in the heat insulation layer and form a bearing platform for bearing the heat-resisting layer. The beneficial effects of the present invention are that the heat insulation rail weighbridge for molten iron weighing is stable in overall structure and long in service life and is resistant to high temperature; the molten iron is prevented from splashing into the gaps around the weighing platform; the rail weighbridge cannot be damaged under the conditions of molten iron heat radiation and little leakage, and the reliable, accurate and stable operation of a weighing and metering system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of iron and steel metallurgy high-temperature hot-melt weighing, in particular to a heat-insulated track scale for weighing molten iron and a laying method thereof. Background technique [0002] Weighing of molten iron in the blast furnace is necessary during the tapping process. First, it can control the amount of iron tapping. Second, it can know the actual delivery amount of each pot. Third, it can be used as the basis for the swing of the swing chute. However, in the prior art, many ironworks use traditional track scales, and there is a certain gap between the weighing platform and the surrounding of the traditional track scales. If metallurgical high-temperature hot-melt molten iron or molten steel leaks or splashes into it, if it is stuck with the weighing platform , it will affect the accurate weighing of the metering system, and the heat radiation (baking) generated by metallurgical high-temperature ...

However, in the prior art, many ironworks use traditional track scales, and there is a certain gap between the weighing platform and the surrounding of the traditional track scales. If metallurgical high-temperature hot-melt molten iron or molten steel leaks or splashes into it, if it is stuck with the weighing platform , it will affect the accurate weighing of the metering system, and the heat radiation (baking) generated by metallurgical high-temperature melting will also cause damage to the track scale. In the prior art, refractory bricks are laid on the surface of the track scale to prevent metallurgical high-temperature melting The damage caused to the track scale, but the laying of refractory bricks on the weighing platform will cause unevenness and structural instability, so the reliable, accurate and stable operation of the weighing and measuring system in high temperature and harsh environments cannot be guaranteed
