Steel ingot teeming runner system

Abstract

The invention provides a steel ingot teeming runner system which comprises vertical cast tube, horizontal cast tubes, mold bottom bricks and a second kind center brick for connecting the vertical cast tube and the horizontal cast tubes, wherein the vertical cast tubes comprise funneled bricks, a plurality of cast tube bricks arranged below the funneled bricks, a first kind center brick connected between the funneled brick and the cast tube bricks and a joint brick for connecting the cast tube bricks and the second kind center brick; and the horizontal cast tubes comprise runner bricks and end runner bricks, the runner bricks are connected with the second kind center brick, and the end runner bricks are connected with tail ends of the runner bricks.

Description

technical field [0001] The invention relates to a flow steel system for pouring steel ingots. Background technique [0002] In the existing steel ingot smelting technology, 30tEBT+120tLFV is mainly used for smelting. Figure 11 and Figure 12 Shown is the stereogram and front view of the existing flow steel system. Such as Figure 11 and Figure 12 As shown, the existing flow steel system produces six steel ingots per tray. The flow steel system includes funnel brick 2', cast pipe brick 1', 3', center brick 6', flow steel brick 8', 7', flow steel tail brick 9' and mold bottom brick 10'. The existing flow steel system casts 3 trays of 16 ingots per furnace (6 in the first tray, 6 in the second tray, and 4 ingots in the third tray), and the pouring time is about 50 minutes (about 17 minutes for each tray), using a funnel Brick 2', cast pipe brick 1', 3', center brick 6', flowing steel brick 8', flowing steel tail brick 9' and mold bottom brick 10' are produced in a complet...

AI Technical Summary

Problems solved by technology

[0003] It can be seen from the above that according to the existing pouring system, the pouring time is too long, technical considerations, molten steel cooling is large, the composition gradient of molten steel changes, the quality of steel ingots is unstable, production considerations are difficult to organize, and safety hazards are high;

[0004] In addition, the central brick 6' for pouring is hexagonal, with sharp edges inside, and the refractory material is easy to fall off when the molten steel flows through, causing molten steel pollution; there is no buffer section for the molten steel flow rate, the molten steel punching process is too fast, and there is slag curling in the production steel ingot and secondary shrinkage holes and other quality hazards; flat buckles are used between the tail brick and the bottom brick of the mold, and there is often misalignment between the two, resulting in different rise heights of the 6 steel ingots in the plate during the punching process, resulting in some steel ingots scrapped
