Abstract
The utility model relates to distribution equipment for a bell-less top of an ironmaking blast furnace, in particular to an integral welding-free distribution chute of the ironmaking blast furnace, which comprises an outer shell and lining plates, and is characterized in that the outer shell is integrally cast and formed, and is internally embedded a lining, the lining is formed by embedding a plurality of lining plates which are respectively formed by embedding a plurality of wear-resistant alloy blocks, and the bottom of the outer shell is fixed with a heat-resistant protective plate. According to the integral welding-free distribution chute, the defect that the existing distribution chute is not wear-resistant, corrosion-resistant and impact-resistant, and has the service life which can not reach the production requirements is overcome. The integral welding-free distribution chute disclosed by the utility model has the advantages of wear resistance, impact resistance, corrosion resistance, long service and convenience in replacement, can greatly reduce the replacement frequency and time of the distribution chute, and reduces the production cost.
Description
Technical field
The utility model relates to a kind of iron-smelting blast furnace without the Fabric material equipment of clock furnace roof, specifically a kind of whole welding Fabric material chute of iron-smelting blast furnace.
Background technology
In the production process of blast furnace ironmaking, often need a kind of equipment to feed to blast furnace roof and the Fabric material.The general Fabric material chute that adopts is for feeding to blast furnace roof and the Fabric material now.Fabric material chute is the key equipment toward blast furnace roof is feeded and Fabric expects.When blast furnace needs when filling with substance, Fabric material chute is driven by transmission rig, with different angles (general 11 °～44 °), different speed, different directions, omnibearing work, material is through the interior circle of Fabric material chute, along the surface of abrasion-proof backing block, washing away incessantly abrasion-proof backing block, at last material is spread to the furnace roof charge level.There is the pressure of 0.2 ~ 0.25mPa on blast furnace charge level top, and when blast furnace worked, Fabric material chute ceaselessly rotated, and is constantly changing angle.At this moment with pressure ground air-flow (coal gas and sulphur etc. are contained in the air-flow the inside), constantly wash away and corroding the case surface of Fabric material chute.The high temperature that the furnace roof charge level is 300 ℃ and instantaneous 500 ℃ high bake Fabric material chute case surface, and Fabric material chute is exactly to work under such an enviroment.The liner plate of existing Fabric material chute is that whole stainless steel plate is welded, and it has advantages of simple in structure, and is not wear-resisting, not corrosion-resistant, not shock-resistant but it has, and does not reach the defective of production requirement work-ing life.After Fabric material chute has worn and torn, often need integral replacing, so just cause very large waste, and change Fabric and expect that chute is the maintenance engineering of a complexity, owing to change the cooperation that Fabric material chute needs production technique, such as damping down blowing out, gas treatment etc., each blast furnace need stop production more than 8 hours, time of recovery after the blast furnace air-supply is therefore, very large on the stable high yield impact of blast furnace in addition.In large Research for Feeding Raw Materials System production process of modern times, the work-ing life wear-resisting, corrosion-resistant, shock-resistant, extension device that solves equipment is very important.
Summary of the invention
The problem of technology to be solved in the utility model is exactly the defective for existing Fabric material chute, provides easily novel Fabric material chute of a kind of wear-resisting, high temperature resistant, corrosion-resistant, long service life, replacing, to remedy the deficiency of currently available products.
The technical solution adopted in the utility model is: it comprises shell and liner plate, it is characterized in that: shell integral cast moulding, inlay liner in the shell, liner is inlayed by the polylith liner plate and is formed, liner plate is inlayed by a plurality of wear-resisting alloy blocks and is formed, and outer casing bottom is fixed with heat-resisting protective shield.Described shell is semi-circular groove or rectangular tank.
Shell of the present utility model is formed by high temperature resistant heavy molten steel monoblock casting; this structure is not only high temperature resistant but also corrosion-resistant, inlays liner plate in the shell, when material down impacts; because the backing strap that has material to form is protected housing, has greatly strengthened shock resistance and the wear-resistant ability of equipment.The utlity model has wear-resisting, shock-resistant, corrosion-resistant, long service life, change easily advantage, the utility model can reduce number of times and the time of changing Fabric material chute greatly, has reduced production cost.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1 and Figure 2, the utility model comprises shell 1 and liner 2, shell 1 integral cast moulding, inlay liner 2 in the shell 1, liner 2 is inlayed by polylith liner plate 3 and is formed, and liner plate 3 is inlayed by a plurality of wear-resisting alloy blocks 4 and formed, and shell 1 bottom is fixed with heat-resisting protective shield 5.As shown in Figure 3, described shell 1 is semi-circular groove or rectangular tank.
Claims (2)
1. a whole welding Fabric expects chute, and it comprises shell and liner plate, it is characterized in that: shell integral cast moulding, inlay liner in the shell, liner is inlayed by the polylith liner plate and is formed, and liner plate is inlayed by a plurality of wear-resisting alloy blocks and formed, and outer casing bottom is fixed with heat-resisting protective shield.
2. according to claim 1 whole welding Fabric material chute, it is characterized in that: described shell is semi-circular groove or rectangular tank.
