Abstract
The invention discloses an electric baking device for a casting steel ladle, which is characterized by mainly comprising a sealing cover, a hanger, more than two electric heating rods, a holder and a thermocouple, the electric heating rods penetrate through the sealing cover, the upper ends of the electric heating rods are hung on the hanger, the lower ends of the electric heating rods are connected onto the holder, and the thermocouple penetrating through the sealing cover is arranged among the electric heating rods. The steel ladle is baked by the electric baking device, so that high heat efficiency, fine tightness, high heat utilization rate and temperature uniformity are achieved. Baking temperature and time can be automatically adjusted according to the process requirement of the steel ladle on baking, clean energy is used and saved, consumption is reduced, and the electric baking device is simple in structure and convenient in operation.
Description
Technical field
The invention belongs to casting field, be specifically related to a kind of casting with ladle electricity apparatus for baking.
Background technology
Ladle is widely used in cast steel industry, be used for accepting molten steel and with molten steel pour into or rising pouring in casting mold, obtain a kind of equipment of foundry goods, also be applied to the molten steel external refining, like equipment such as ladle furnace refining method (LF method), VOD method, TN methods.
Newly build ladle by laying bricks or stones or only change working lining and the normal ladle that uses (after comprising light maintenance), should pass through sufficient baking before use, in order to avoid cause molten steel to absorb gas, and make the too fast temperature drop of molten steel.Newly build the baking of ladle by laying bricks or stones and can quicken the very fast sintering of fire clay in the brickwork joint.
Cast is the important procedure that cast steel is produced, and directly influences casting quality.Therefore carry out ladle build by laying bricks or stones and toast most important.Traditional ladle baking roughly has: toast with fuel nozzle (heavy oil, diesel oil) (1); (2) toast with gas nozzle (liquefied petroleum gas, coke-stove gas); (3) toast with hot waste gas; (4) with coke or firewood baking.Most fuel nozzle baking or the gas nozzle baking ladles of adopting of medium-and-large-sized cast steel enterprise.Below all there is weak point.
(1) heat utilization efficiency is lower;
(2) fuel nozzle (heavy oil, diesel oil) baking, it is insufficient to burn, and energy consumption is big, flue gas, hot gas, noise pollution surrounding working environment;
(3) gas nozzle (coke-stove gas) baking will be built gas generator or gas station, has increased investment of devices.
(4) toast ladle with liquefied petroleum gas, air consumption is bigger, and operating cost is high.
Summary of the invention
The objective of the invention is for overcoming the deficiency of prior art, and provide a kind of casting with ladle electricity apparatus for baking, this device thermal efficiency is high, can ladle be heated to the baking process requirement, and is energy-saving and cost-reducing, free from environmental pollution, simple in structure, easy to operate.
The present invention seeks to realize through following technical scheme:
A kind of casting is with ladle electricity apparatus for baking; Mainly by seal cover and the suspension bracket that is welded as a whole with seal cover, electrical bar, fixed mount; Thermoelectric corner is formed, and electrical bar passes the seal cover upper end and is hung on the suspension bracket, and the lower end is connected on the fixed mount; Thermocouple passes seal cover and is arranged between the electrical bar, and electrical bar is provided with more than 2.
Said electrical bar mainly is made up of joint, refractory material cover, resistance wire, ceramic fixed cover, fixed bar, nut, fixed bar protective sleeve, and joint connects power supply and resistance wire; The refractory material cover encases one of electrical bar, and ceramic fixed cover entangles fixed bar, and resistance wire is arranged in the ceramic fixed cover; Inside and outside each row is annular and is uniformly distributed with, and is installed in then on the fixed bar of protective sleeve; The other end is fixed in the refractory material cover, with the fastening two ends of nut.
Described electric roaster seal cover size and ladle mouth coupling, inner chamber is filled with refractory fibre;
Resistance wire is processed by the nichrome steel wire, diameter D8-10mm;
The resistance wire stator is processed by high temperature ceramic material;
Refractory material cover and fixed bar protective sleeve are formed by fire clay compacting roasting;
The wiring of electricity roaster electrical bar is star-star connection, and 380V, the power of every group of electrical bar are 8-9KW.
Advantage of the present invention is:
1, the thermal efficiency is high, good airproof performance, and heat utilization efficiency is high, and temperature is even;
2,, can source clean, during ladle baking, do not pollute surrounding environment;
3, simple in structure, easy to operate, expense is lower.
