Sloping hearth furnace is one of major equipment of producing hot rolled seamless steel tube, mainly is the Thermal Equipment of heating before the round steel billet perforation, and the structure of sloping hearth furnace comprises feeding gate, and feeding gate inwardly is conveying passage, i.e. burner hearth.Round steel billet in the preheating channel of sloping hearth furnace obtains preheating; The diapire of burner hearth is skewed and is brickwork construction, round steel billet is taken advantage of a situation tumble to heat tunnel, finishes reinforced process and heating.The top of burner hearth is provided with furnace roof, and furnace roof is provided with firebreak, can strengthen burner and conduct heat, and improves the utilization ratio of furnace heat, reduces the flue gas thermosteresis, has energy-conserving action; Also can offset the furnace pressure that causes because of oblique furnace bottom potential difference and increase progressively, thereby can reduce " emerging " and " suction " phenomenon of fire door hole.
Traditional sloping hearth furnace is fixed in firebreak on the furnace roof, and steel billet immobilizes by face, and the steel billet specification kind of therefore processing is restricted.Especially when producing the weldless steel tube of large specification, traditional sloping hearth furnace does not have versatility; Therefore, producer often must increase an external coordination expense on a small scale; And large-scale corporation with good conditionsi can set up the sloping hearth furnace of different size, has but additionally increased expensive installation cost, mounting cost etc., has also taken the bulk factory site of many preciousnesses, and most of sloping hearth furnace often is in idle state, can not reach and make the best use of everything.In the time of firebreak palpus maintain and replace, dismounting is often very difficult, and human cost is larger, and man-hour is longer, may incur loss through delay production project.
In sum, traditional sloping hearth furnace production cost is large, and cost performance is low; The dismounting difficulty, human cost is large.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of cost performance high, and dismounting simply can be processed the economical sloping hearth furnace of different size steel billet.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of economical sloping hearth furnace of processing the different size steel billet, has furnace roof, the below of furnace roof begins to be provided with successively preheating channel and heat tunnel from opening for feed, furnace roof is provided with the multiple tracks firebreak, and firebreak is installed on the furnace roof by hoisting appliance.
The utility model can pass through optionally lifting firebreak of hoisting appliance according to the steel billet of processing different size, suitably reserves to steel billet and passes through the space, farthest strengthening burner conducts heat, improve the utilization ratio of furnace heat, reduced the flue gas thermosteresis, good energy-conserving effect.The utility model can be processed the steel billet of different size, has versatility, does not need external coordination, needn't set up extra sloping hearth furnace, has reached the state of making the best use of everything; Therefore, its production cost is little, and cost performance is high.In addition, in the time of firebreak palpus maintain and replace, can pull down smoothly and the maintain and replace firebreak by hoisting appliance, simple in structure, easy accessibility.
As preferably, in order to take full advantage of factory resources, hoisting appliance is driving.Existing driving has portable driving switch usually, by the driving on-off control, by observing steel billet in the material toggling mouth of sloping hearth furnace by the space, can realize precise fine-adjustment again.
Further, in order to prolong the work-ing life of firebreak, firebreak is communicated with the low temperature running water pipe for the cooling firebreak.
As preferably, in order to realize the smooth lifting of firebreak, the low temperature running water pipe is metallic hose.
As preferably, conduct heat in order farthest to strengthen burner, improve the utilization ratio of furnace heat, reduce the flue gas thermosteresis, and counteracting increases progressively because of the furnace pressure that oblique furnace bottom potential difference causes; Preheating channel respectively is provided with firebreak with the furnace roof at transition position, preheating channel place and the heat tunnel place of heat tunnel.
As preferably, in order to bear high temperature, the material of firebreak is high alumina castable.
The beneficial effects of the utility model are:
1. good energy-conserving effect: the utility model can be according to the steel billet of processing different size, can pass through optionally lifting firebreak of hoisting appliance, suitably reserve by the space to steel billet, farthest strengthen burner and conduct heat, improve the utilization ratio of furnace heat, reduced the flue gas thermosteresis;
2. production cost is little, and cost performance is high: the utility model can be processed the steel billet of different size, has versatility, does not need external coordination, needn't set up extra sloping hearth furnace, has reached the state of making the best use of everything;
3. simple in structure, easy accessibility: in the time of firebreak palpus maintain and replace, can pull down smoothly and the maintain and replace firebreak by hoisting appliance;
4. the long service life of firebreak: firebreak is communicated with the low temperature running water pipe for the cooling firebreak.
