Abstract
The utility model discloses a holding furnace door which is hemispherical. The holding furnace door is formed by an iron outer shell. The interior of the holding furnace door is filled with fireproof materials, and a circle of groove is formed in the position, where the bottom of the holding furnace door and a furnace opening are sealed, of the bottom of the holding furnace door, and provided with packing to carry out sealing. Due to the fact that the high-temperature resistant packing with the better sealing performance is additionally arranged in the circle of groove formed in the bottom of the holding furnace door, the holding furnace door and a furnace body can be better sealed, even if materials are required to be replaced after the holding furnace door is used for a period of time, only the packing in the groove is required to be replaced, a holding furnace is better sealed, the mode that a heat preservation asbestos board is required to be replaced every time when aluminum is added, and the casting cost of vehicle wheels can be effectively reduced.
Description
Technical field
The utility model relates to low pressure casting equipment field, relates in particular to a kind of holding furnace fire door.
Background technology
China's aluminum alloy wheel of vehicle more than 80% adopts low pressure casting mode to be shaped at present, it is low that this forging type has pressure, fill type steady, the feature that shaped casting compactness is good, and air injection machine is as most important manufacturing equipment in aluminum vehicle wheel low pressure casting process, not only be related to the cost structure of aluminum vehicle wheel, and the quality of product is had to important impact, in multiple parts of air injection machine, holding furnace plays guarantee temperature of aluminum liquid, for being shaped for the effect of stream, due to need switch frequently, so the fire door of integral type pouring type is very easy to damage, thereby cause seal degree constantly to reduce, many manufacturing enterprises often at new fire door with just carrying out sealing door with insulation asbestos board after a period of time, this way that often adds aluminum solutions and just need to place an asbestos board has increased the cost of casting aluminum wheels greatly.
Summary of the invention
The purpose of this utility model be overcome existing holding furnace oven door sealing bad, often add the problem that a secondary aluminium liquid will add an asbestos board, a kind of can seal for a long time, low cost holding furnace fire door is provided.
The concrete technical scheme that realizes above object is: a kind of holding furnace fire door, this fire door is hemispherical, formed by iron shell, in fire door, fill with refractory material, position in fire door bottom and fire door sealing is provided with a circle groove, in groove, seal with packing, high temperature resistant owing to being equipped with in a circle groove set bottom fire door, the more packing of sealing, thereby make fire door and body of heater can realize better sealing, even need more conversion materials after a period of time is used, also only need to change packing wherein, therefore not only can make holding furnace more seal, and change and add aluminium at every turn and just need to change the way of insulation asbestos board, can effectively reduce the casting cost of wheel.
Accompanying drawing explanation
Fig. 1 the utility model structural representation.
concrete embodiment
As shown in Figure 1, a kind of holding furnace fire door, this fire door is hemispherical, shell is made up of iron material matter, inside there is the refractory material 1 of filling, in the seal 3 at fire door bottom and furnace sealing place, be provided with a circle groove, in groove, add a circle sealed packing 2, can make this fire door there is better sealing and lower cost by above design.
Claims (1)
1. a holding furnace fire door, it is characterized in that: this fire door is hemispherical, shell is made up of iron material matter, inside has the refractory material (1) of filling, in the seal (3) at fire door bottom and furnace sealing place, be provided with a circle groove, in groove, add a circle sealed packing (2).
