Abstract
The invention relates to a water-cooling electrode ring protection device for an electric arc melting furnace. The water-cooling electrode ring protection device is composed of a fixed support, safety fastening chains I/II, a high-voltage insulator, connecting plates I/II and the like. According to the water-cooling electrode ring protection device for the electric arc melting furnace, a water-cooling electrode ring is fixed to an electric arc furnace supporting arm through the fixed support, the safety fastening chains I/II, high-voltage insulator mica, the connecting plates I/II and the like, and the water-cooling electrode ring is prevented from falling into molten steel. The high-voltage insulator is composed of multiple layers of the mica capable of bearing the impact of high voltages and large currents, the high voltages and large currents generated when the electric arc furnace works are isolated from the water-cooling electrode ring, a furnace body and an operation platform, the service life of a furnace cover is prolonged, production cost is lowered, and economic benefits are improved. Personal accidents and equipment accidents caused by the explosion of the molten steel are eradicated.
Description
Affiliated technical field
The present invention relates to a kind of water cooled electrode circle protective device, be particularly useful for water cooled electrode circle protective device in electric arc furnaces fusion process for metallurgy and casting, belong to mechanical metallurgy device security field.
Background technology
Metallurgical and casting is used in electric arc furnaces fusion process, and the Main Function of water cooled electrode circle is cool furnace tops and prevents anodizing.At present, water cooled electrode circle level is generally all freely placed on roof brick, without any fixture.This structure has the following disadvantages:
1, the refractory brick of bell inner side is subject to for a long time high-temperature furnace gas and toasts, washes away, corrodes, the thickness of refractory brick reduces gradually, the little bell (generally monthly changing once) of will changing to a certain extent time of refractory brick thickness, otherwise bell refractory brick is when caving at any time, and water-cooled electrode collar is also fallen in molten steel thereupon.
2, due to liquid steel temperature in melting stage up to 1700 ℃, after being full of the water cooled electrode circle of cooling circulating water and entering in high-temperature molten steel, recirculated water volume, because expanding and blast rapidly, will cause great equipment or personal injury.
Summary of the invention
The object of the invention is to overcome the weak point of existing water cooled electrode circle, a kind of water cooled electrode circle safety guard is provided.
A kind of melting electric arc furnace water cooled electrode collar safety guard of the present invention, main hold-down support, is fastened securely the compositions such as chain I/II, high voltage insulator, connecting plate I/II.
Described melting electric arc furnace water cooled electrode collar safety guard, by hold-down support, be fastened securely chain I/II, high voltage insulator mica, connecting plate I/II etc. water cooled electrode circle is fixed to electric arc furnaces support arm, avoids water cooled electrode circle to fall in molten steel; The high voltage insulator forming by can be born the mica of high voltage, heavy current impact by multilayer, the high voltage producing when electric arc furnaces is worked, large electric current completely cut off and come with water cooled electrode circle, body of heater, operating platform, extended the service life of bell, reduce production cost, improved economic benefit.
The invention has the beneficial effects as follows:
1, direct economic benefit: bell has once been brought up to replacing in present every six months once by changing every month, can save every year ten of bells, and approximately 8500 yuan of left and right of the cost of each bell, are often only one of bell and just can economize on the use of funds 85000 yuan.In addition, bell work can also be engaged in other work after finishing building bell, creates again every year 159226.9 yuan of the output values (counting per capita with reference to 2011) more.
2, in all directions: stopped the person that molten steel blast causes and the generation of equipment breakdown.
Accompanying drawing explanation
Fig. 1, Fig. 2, Fig. 3 are structural representations of the present invention,
In figure: 1-electric arc furnaces support arm, 2-water cooled cover circle, 3-refractory brick bell body, 4-water cooled electrode circle, 5-is fastened securely chain I, 6-high voltage insulator, 7-hold-down support, 8-is fastened securely chain II, 9-gusset piece I, 10-gusset piece II, 11-bolt and nut.
The specific embodiment
As shown in the figure: the transverse arm position that hold-down support (7) is fixed on to electric arc furnaces support arm (1), the one end that is fastened securely chain I (5) is connected on hold-down support (7), the other end and gusset piece II (10) are connected, gusset piece I (the 9)/gusset piece II (10) of high voltage insulator (6) both sides tightens together with bolt and nut, the one end and the gusset piece I (9) that are fastened securely chain II (8) are connected, another section connects water cooled electrode circle (4), electric arc furnace water cooled electrode collar (4) just partly connects and tightens together with the transverse arm of electric arc furnaces supporting arm (1) like this, when the brick of bell falls, avoided electric arc furnace water cooled electrode collar (4) to fall in high-temperature molten steel with roof brick.
Claims (5)
1. a water cooled electrode circle protective device, is characterized in that: adopt hold-down support, be fastened securely chain I/II, high voltage insulator, connecting plate I/II etc., water cooled electrode circle and electric arc furnaces supporting arm transverse arm are fixed together.
