Abstract

The utility model provides a liquid outlet launder for a calcium carbide furnace. The liquid outlet launder comprises lining bricks and a bracket. The lining bricks are made of materials combining silicon nitride and silicon carbide and embedded in the bracket. A structure for feeding cooling water is omitted, and accordingly risks of cooling water leakage are avoided. The lining bricks are made of the materials combining silicon nitride and silicon carbide, and the materials have the advantages of thermostability, erosion resistance, long service life and the like. The lining bricks are compressed by a vibration compressor, so that the density and uniformity of the lining bricks are guaranteed, and thermal shock resistance and wear resistance of the lining bricks are improved.

Description

A kind of calcium carbide furnace liquid outlet port chute
Technical field
The utility model relates to a kind of furnace of calcium carbide production equipment, especially a kind of calcium carbide furnace liquid outlet port chute.
Background technology
The calcium carbide furnace liquid outlet port chute adopts the cast steel water through structure at present, and this type of chute resistance to elevated temperatures is not good, and scour resistance and wearability are not high, and service life is short; And be prone to the perforation drainage in using, just must blowing out repair in case occur leaking, leak and seriously can cause the calcium carbide liquation to meet the serious accident of water blast; In addition, calcium carbide easily cooling crusts at chute, just can reuse after must clearing up, and labor intensive is many, delays man-hour.
Summary of the invention
The purpose of the utility model patent provides a kind of calcium carbide furnace liquid outlet port chute, can overcome the existing deficiency of cast steel liquid outlet chute, provide simple to operate safe, safeguard that cleaning is easy and quick, and the calcium carbide furnace liquid outlet port chute of long service life, service life that can Effective Raise calcium carbide furnace liquid outlet port chute, reduce maintenance frequency, thereby improve equipment operation rate, reduce the product material consumption.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of calcium carbide furnace liquid outlet port chute is characterized in that: described liquid outlet chute comprises liner and bracket, and liner is silicon nitride combined silicon carbide material, and liner is embedded in the bracket.
To improvement of the technical scheme: described liner is tiled by a plurality of lining bricks and forms.
To further improvement in the technical proposal: the lining brick of described liner is the wedge form wedge form dovetail shape, and bracket is provided with many wedge form wedge form dovetail grooves corresponding with lining brick, and liner and bracket become one by fire clay is bonding.
Beneficial effect:
Calcium carbide furnace liquid outlet port chute described in the utility model cancelled logical cooling Water structure, the danger of having avoided cooling water to reveal, and liner tile adopts the silicon nitride combined silicon carbide material to make, the advantages such as that this material has is high temperature resistant, resistance to erosion, long service life.The silicon nitride combined silicon carbide liner tile adopts the compacting of vibration press to form, and guarantees product density and uniformity, has improved thermal shock resistance and the wearability of product.The silicon nitride combined silicon carbide liner tile is designed to be with the dovetail wedge shape, and sound construction is conveniently built by laying bricks or stones and changed; And can prevent expands with heat and contract with cold causes cracking.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is band dovetail wedge conformal silicon nitride based on silicon carbide matter liner tile.
Fig. 3 is the cast steel bracket.
The specific embodiment
A kind of calcium carbide furnace liquid outlet port chute of the utility model as shown in Figure 1, described liquid outlet chute comprises liner 1 and bracket 2, and liner 1 is silicon nitride combined silicon carbide material, and liner 1 is embedded in the bracket 2; Liner 1 is tiled by a plurality of lining bricks 3 and forms, and described lining brick 3 is the wedge form wedge form dovetail shape, and bracket 2 is provided with many wedge form wedge form dovetail grooves corresponding with lining brick 3, and liner 1 becomes one by fire clay is bonding with bracket 2.
At first make steel mold and heat-treat according to shape shown in Figure 2, detachment mode is adopted in Mold Making, makes demoulding smooth, improves yield rate; After the set of molds of having made installed, be installed on the vibration moulding forcing press, carry out theoretical calculated weight by 2.60g/cm3 density and take by weighing mixed carborundum+metallic silicon power+materials such as bond, join and carry out moulding in the die cavity; The base substrate of forming is dried, burn till the formation liner tile through large-scale nitriding furnace nitrogenize.
At first make master mold according to shape shown in Figure 3, make sand mold with master mold.Molten steel is poured into cooling formation cast steel bracket in the sand mold chamber; The cast steel bracket is taken out the cleaning finishing from sand mold.The silicon nitride combined silicon carbide liner tile inlayed to build by laying bricks or stones at the cast steel bracket with supporting fire clay produce this product.
Calcium carbide furnace liquid outlet port chute described in the utility model also can be used for other mineral hot furnace liquid outlets.
