Description
Technical Field
The utility model relates to a feeding hole chute for steel slag treatment, and belongs to the technical field of steel-making steel slag treatment equipment in the metallurgical industry.
Background
During the steel-making process, a great deal of steel slag is produced, and the temperature is 600-800 ℃. At present, the steel slag has two treatment modes: one is directly hot splashed in a slag pool, and the powder is cooled by water, braised and slag discharged after 40 hours to achieve the purpose of recycling; the other method is to directly treat the slag in a roller slag treatment mode to achieve the effect of recycling. The drawback of the first mode is that a large area is needed, a large amount of water is needed for cooling, manpower and material resources are wasted, explosion easily occurs in the process of pouring and boiling water and thermally braising the slag ladle, and dangerous hidden dangers exist in the treatment process. The second roller slag treatment mode is that high-temperature steel slag enters a roller through a feed inlet to be quenched, then the steel ball is crushed, screened and slag is discharged, the mode is advanced, but a chute of the feed inlet is only coated with refractory soil simply, the refractory soil sprayed in a slag chute is impacted by high-temperature slag flow, and the refractory soil in the slag chute is easy to fall off, so that the slag chute is burnt out, and the slag chute is cooled and cracked to cause accidents such as steel slag external silting.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a feeding hole chute for treating steel slag, which can avoid the phenomenon that steel slag is externally silted due to the fact that a chute is burnt by the impact of high-temperature steel slag, reduce the labor intensity and the danger of operators and solve the problems in the background art.
The technical scheme of the utility model is as follows:
a feed inlet chute for steel slag treatment comprises a slag sliding body, a cast steel sleeve, a small lining plate, a v-shaped lining plate, a fixing bolt and a lifting lug, wherein the upper part of the slag sliding body is in a hollow frustum shape with a large upper part and a small lower part, the lower part of the slag sliding body is in a hollow cylindrical shape, the top of the slag sliding body is a slag inlet, the bottom of the slag sliding body is a slag outlet, the cast steel sleeve is in a hollow frustum shape matched with the upper part of the slag sliding body, the cast steel sleeve is fixed on the inner wall of the upper part of the slag sliding body, and the top end of the cast steel sleeve is provided with two symmetrically arranged lifting lugs; the small lining plate and the v-shaped lining plate are respectively fixed at the lower part of the slag chute body through fixing bolts.
The small lining plate is rectangular, and the V-shaped lining plate is V-shaped with a downward opening.
The upper part of the slag sliding body is in a hollow quadrangular frustum pyramid shape, the lower part of the slag sliding body is in a hollow quadrangular prism shape, and the cross sections of the upper part and the lower part of the slag sliding body are both square.
When the chute body is used, the chute body is firstly stably seated on the bracket above the roller, and then the cast steel sleeve, the heat-resistant small lining plate and the heat-resistant V-shaped lining plate are embedded in the chute body, so that when steel slag flows into the chute from the slag pot in an inclined manner, high-temperature steel slag can be well and smoothly guided into the roller, and the chute shell is not subjected to any impact and burning loss.
The utility model has the beneficial effects that: the slag chute can be prevented from being burnt by the impact of high-temperature steel slag, so that the steel slag is externally silted, and the labor intensity and the danger of operators are reduced.

in the figure: the device comprises a slag chute 1, a cast steel sleeve 2, a heat-resistant small lining plate 3, a heat-resistant v-shaped lining plate 4, a fixing bolt 5 and a lifting lug 6.
Detailed Description
The utility model is further illustrated by way of example in the following with reference to the accompanying drawings.
Referring to the attached drawings 1-4, a feeding hole chute for steel slag treatment comprises a slag sliding body 1, a cast steel sleeve 2, a small lining plate 3, a v-shaped lining plate 4, a fixing bolt 5 and lifting lugs 6, wherein the upper part of the slag sliding body 1 is in a hollow frustum shape with a large upper part and a small lower part, the lower part of the slag sliding body 1 is in a hollow cylindrical shape, the top of the slag sliding body 1 is a slag inlet, the bottom of the slag sliding body 1 is a slag outlet, the cast steel sleeve 2 is in a hollow frustum shape matched with the upper part of the slag sliding body 1, the cast steel sleeve 2 is fixed on the inner wall of the upper part of the slag sliding body 1, and the top end of the cast steel sleeve 2 is provided with two symmetrically arranged lifting lugs 6; the small lining plate 3 and the v-shaped lining plate 4 are respectively fixed at the lower part of the slag chute 1 through fixing bolts 5.
In the present embodiment, referring to FIGS. 1 to 4, the chute 1: the steel plate is made of Q235 material and has the thickness of 30 mm;
cast steel bush 2: the material is cast by adopting a ZG230-450 material with the thickness of 80 mm;
heat-resistant small liner 3 and heat-resistant v-shaped liner 4: the material ZG230-450 is made of a material with the thickness of 80mm by die casting and die casting;
lifting lug 6: the material is manufactured by adopting ZG230-450 material with the thickness of 80mm through die casting.
After the cast steel bushing 2 is successfully cast, the lifting lug 6 is lifted to be directly seated and lined in the chute body 1, a gap of 30mm is reserved between the cast steel bushing 2 and the chute body 1, and replacement is convenient.
12 phi 45mm bolt holes matched with the chute body 1 are reserved when the heat-resistant small lining plate 3 and the heat-resistant v-shaped lining plate 4 are cast, and when the chute is used, the heat-resistant small lining plate 3 and the heat-resistant v-shaped lining plate 4 are fastened on the inner side of the chute body 1 by the phi 45mm bolts.
The working principle is as follows: referring to the attached figure 1, during steel slag treatment, a slag tank is firstly tipped, the steel slag is poured into a slag chute downstream, the steel slag directly impacts a cast steel sleeve 2 and continuously flows to a heat-resistant small lining plate 3 and a heat-resistant v-shaped lining plate 4, the heat-resistant v-shaped lining plate is clamped on the upper part of a diverter plate in a roller, and the steel slag is smoothly divided into two parts to flow into the roller for cold quenching and screening treatment. Because the chute body 1 is protected by the cast steel sleeve 2, the heat-resistant small lining plate 3 and the heat-resistant V-shaped lining plate 4, the chute body is not scoured by high-temperature steel slag, residual steel slag in the lining naturally falls off after being cooled by water, and the lining is continuously used.
