Abstract
The utility model discloses an air-cooling combined hearth roller. The air-cooling combined hearth roller is realized by adopting the following technical scheme: the hearth roller consists of a fire-resistant layer, a stainless steel sleeve and a heat-resistant steel core shaft, wherein the fire-resistant layer is fixed on the outer peripheral surface of the stainless steel sleeve and the heat-resistant steel core shaft is arranged in the stainless steel sleeve. The hearth roller achieves the aim of temperature reduction by causing cooling air to pass through the stainless steel sleeve and ensures the temperature of the hearth roller to be lower than the temperature of a hearth. Compared with the existing water cooling method, the air cooling method can remarkably reduce fuel consumption. In the hearth roller, a water circulating system is not used so that apparatus investment is reduced and apparatus maintenance is simplified.
Description
Technical field
The utility model relates to strip hot galvanizing heating furnace field, more particularly, relates to a kind of furnace bottom roll that adopts air cooling.
Background technology
Strip hot galvanizing heating furnace furnace bottom roll adopts water cooling more at present, thereby prevents that furnace bottom roll at high temperature is out of shape.The shortcoming of water-cooled furnace bottom roll is that recirculated water is taken away a large amount of heats, waste fuel.And the circulating water system investment is big, difficult in maintenance.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of air-cooled built-up type furnace bottom roll is provided.
The air-cooled built-up type furnace bottom roll of the utility model, be achieved by following technical proposals, described furnace bottom roll is made up of flame retardant coating, stainless steel sleeve pipe and high temperature steel mandrel, and described flame retardant coating is fixed in stainless steel sleeve pipe periphery, and the high temperature steel mandrel is arranged in the stainless steel sleeve pipe.
In the flame retardant coating described in the utility model along the stainless steel sleeve tubular axis to strengthening ring evenly is set, described strengthening ring is fixed by strengthening gusset and stainless steel sleeve pipe periphery.Described furnace bottom roll cooling air inlet end passes through bearings.Described furnace bottom roll cooling air outlet end supports by two support rollers.
The utility model utilize cooling air from stainless Steel Sleeve by reaching the purpose of cooling, guarantee the temperature of the temperature of furnace bottom roll a little less than burner hearth.Such type of cooling is compared with existing water-cooling pattern, can significantly reduce the loss of fuel.Cancelled water circulation system, can reduce facility investment and simplified apparatus and safeguard.
Description of drawings
Fig. 1 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model is made up of flame retardant coating 1, stainless steel sleeve pipe 2 and high temperature steel mandrel 3, and described flame retardant coating is fixed in stainless steel sleeve pipe periphery, and the high temperature steel mandrel is arranged in the stainless steel sleeve pipe; Because furnace bottom roll is axially longer, for increase its intensity in flame retardant coating along the stainless steel sleeve tubular axis to strengthening ring 4 evenly is set, be that strengthening ring is placed in flame retardant coating, the strengthening ring outer ring body is positioned at the flame retardant coating side face, described strengthening ring is fixed by strengthening gusset and stainless steel sleeve pipe periphery, and the reinforcement gusset is positioned at the strengthening ring inner ring and is spoke-like.Furnace bottom roll cooling air inlet end supports by bearing 6; Because furnace bottom roll cooling air outlet end temperature is too high, damage for preventing that Yin Wendu is too high, furnace bottom roll cooling air outlet end supports by two support rollers 7.
Cooling air passes through from stainless Steel Sleeve in the use, takes away the part heat, thereby reaches the purpose of cooling.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineering technical personnel make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.
