Abstract
The utility model relates to a baking inner liner protection frame of a high temperature box type resistance furnace, which guarantees the use of a standby high temperature nozzle for the casting of a continuous casting tundish, such as a split type quartz nozzle, in the continuous casting production of the metallurgy steel-making. The high temperature box type resistance furnace includes a resistance furnace body (1) and an inner liner (2) which is characterized in that a protection frame (3) is disposed inside the inner liner (2). The nozzle of the heated object and the inner liner of the high temperature resistance furnace are separated, thus avoiding damage of the resistance wire and preventing failure of the furnace brick; and meanwhile the nozzle of the furnace is arbitrarily stacked in a fixed range. The utility model guarantees the application effect of the box type resistance furnace, and is stable and highly efficient.
Description
Technical field
The utility model relates to a kind of high temperature box type resistance furnace.Be mainly used in metallurgical steel-making continuous casting when producing, guarantee that the standby high temperature mouth of a river of continuous casting basket pouring is used, for example the split type quartzy mouth of a river.Belong to the steelmaking equipment technical field.
Background technology
When steel-making continuous casting is produced, two kinds of forms of the general employing in the mouth of a river that whenever flow down of tundish: monoblock type and split type.Because it is split type that cost factor, continuous casting originally adopt mostly.But along with steel grade class demand, continuous casting steel quality requirement improve and the development of equipment equipment, at present some enterprises particularly the special steel industry adopt the monoblock type mouth of a river mostly.But because in the actual motion, since all multifactor, cause some monoblock type mouth of a river fractures and accident and will strike mouthful reason of cutting off the water supply, and the split type mouth of a river is still as a kind of necessary means of taking precautions against and remedying causality loss of each steel-making enterprise.
Two kinds of mode of heatings of the general employing in the split type mouth of a river: electrical heating and combustion gas heating.The latter is owing to cost height, standby limited amount and the unsafe reason of naked light is arranged, and adopts few; Factors such as electrical heating is good owing to temperature persistance, reserve level is big, integrated cost is low, safe become continuous casting production equipment first-selection.
But the chamber type electric resistance furnace spoilage of smelter use in the past is higher, mainly be because the mouth of a river that continuous casting uses is all cylinder (tubular type), deposit difficulty at box house, the time have vibration, the collapse phenomenon that causes of distortion to happen occasionally, thereby damage body of heater inner bag, resistance wire, thermocouple and mouth of a river body, make the cabinet-type electric furnace advantage can not get real embodiment.And often all to use up many times in handling failure, and both taken manpower, take money again, utilization rate is not high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of effect that can guarantee that box electricity group stove uses is provided, and the high temperature box type resistance furnace of stability and high efficiency.
The purpose of this utility model is achieved in that a kind of high temperature box type resistance furnace baking inner bag bearer bar, and comprising: resistance furnace body and inner bag are provided with a bearer bar in inner bag.Make to be heated not produce between the object mouth of a river and high temperature resistance furnace internal-lining to contact, the fault of also just having stopped to damage resistance wire, protection firebrick takes place, and self mouth of a river can be stacked arbitrarily in fixing scope simultaneously.
The beneficial effects of the utility model are:
By using the utility model, can guarantee heating nozzle's effect during the electroslag steel smelting, and safety, can not damage the purpose that high temperature resistance furnace body equipment, frame inner nozzle can arbitrarily be stacked.High temperature box type resistance furnace life cycle has in the past been enlarged more than 3 times, improved the high temperature box type resistance furnace utilization rate greatly, reduced maintenance cost.And be convenient to workman's operation aspect the actual use, resistance wire, thermocouple spoilage reduce greatly, strong guarantee continuous casting ordinary production demand and minimizing causality loss.

The specific embodiment
Referring to Fig. 1, Fig. 1 is the general structure schematic diagram of the utility model high temperature box type resistance furnace.As seen from Figure 1, the utility model high temperature box type resistance furnace comprises: resistance furnace body 1 and inner bag 2 are provided with a bearer bar 3 in inner bag 2.
The material of described bearer bar 3 usefulness high temperature resistances is made, and has and can plug function, is convenient to replace; Simultaneously temperature element thermocouple 4 is moved to resistance furnace body 1 tip position of not placing bearer bar 3 positions, guarantee not by the mouth of a river, framework collision.
