Abstract
The invention provides an electroslag steel energy-saving combined rectangular crystallizer, which is mainly used for smelting of square, flat and a variety of ingots of different sizes. The crystallizer consists of at least four independent units. Each of the independent units includes a reference unit, and a connection unit. The reference unit is a closed cavity, the liner plate of which is welded with an arc current homogenizing plate and several guide plates. The guide plates are distributed with through holes uniformly. And the current direction is controlled by the arc current homogenizing plate and the several guide plates. The crystallizer provided in the invention has the advantages of high strength liner structure, long service life, as well as energy saving, is convenient for recombination to change the ingot shape and size, and is more convenient for partial replacement of a damaged crystallizer.
Description
Technical field
The present invention relates to a kind of rectangle mold in the special steel electroslag smelting equipment.Have electricity-saving function, adopt novel netted current cooling, standalone feature component units building blocks assembling combination mode, accomplish multiple ingot shape melting square, the flat different size.
Background technology
At present; Known electroslag smelting in the special steel industry; Be to form short net by consumable electrode, dummy electrode, the X-former end of to mold, consumable electrode (fusible raw material steel ingot) is accomplished the remelting recrystallize in mold, and mold is exactly an extraordinary mould of accomplishing metal remelting recrystallize.
In traditional rectangular mold structure form, often adopt monobloc(k)type (seeing diagrammatic sketch 1, Fig. 2) two joint piecing assemblys (seeing diagrammatic sketch 3, Fig. 4) or divide half dock (seeing diagrammatic sketch 5, Fig. 6) structure.Traditional rectangular mold characteristics: simple in structure, easy to manufacture, but be not easy to standardization of products production, management and manufacturing in batches, be not easy to specification series design how wide in variety.Board-like in traditional thermal energy exchange on the corner have eddy current and a stagnant area, and the local heat radiation of influence also possibly produce the air chamber district, can make mold damage product defects when serious.And toroidal helical ascending manner current Peak Flow Rate affects mold inner bag thermal energy exchange effect (seeing diagrammatic sketch 7, Fig. 8) like this at the mold outer casing inner wall.
Summary of the invention
In order to overcome the drawback of traditional mold, the present invention provides long service life, combined type rectangular electroslag steel mold that energy consumption is little.
The present invention includes several separate units, at least 4 separate units.
Said separate unit comprises reference cell, connector element.
Said reference cell is 4 integer multiple; Said connector element is 2 integer multiple.
The combined of separate unit realizes T shape integral sealing with gasket, and every group of separate unit connection uses two pins, tack bolt to be fastenedly connected.
Said reference cell by steel up and down height expand the enclosed cavity that web plate (1), T2 red copper inner bag bent plate (2), steel radial expansion web plate (3) steel shell (5) are constituted, last lower interface (6) current homogenizing plate (8) flow deflector (9) sewage draining exit (7) constitutes the water route and circulates.
Said connector element; By steel up and down height expand the enclosed cavity that web plate (10), T2 red copper inner bag plate (13), steel radial expansion web plate (11) steel shell (12) are constituted, last lower interface (14) current homogenizing plate (17) flow deflector (18) sewage draining exit (16) constitutes the water route and circulates.Realize energy-saving circuit short circuit output by output wiring terminal (15) and T2 red copper inner bag plate (13).
Gasket of the present invention is provided with between rectangle mold component units, utilizes the inner face of gasket and mold end face formation T shape trim to prevent that the electroslag molten steel from overflowing.Said gasket comprises two kinds, the gasket one of the 90 degree bending angle that the first is shown in Figure 15; It two is rectangular gaskets two shown in Figure 16.
Each connector element bottom of the present invention is provided with secondary (three times) short circuit current output wiring terminal, energy-conservation when realizing the steel ingot refusion and smelting.
Combination of the present invention comprises combination or 4n reference cell and the combination between 2n connector element between at least four reference cells.
The present invention sets up the heat exchange method of novel current in each separate unit.
The present invention is resolved into the rectangle mold by many and is formed the independent standard unit, according to the demand of user's steel ingot ingot shape, standard cell is carried out the cord wood combination, reaches user's working condition requirement.Assembly unit again in the time of can also realizing user's product size, change in shape.And when the local generation of mold is lost efficacy, did local unit replacement, and prolonged one-piece construction work-ing life greatly and reduced manufacturing cost.The rectangle mold fully takes into account the application and advanced thermal energy exchange mode of power-saving technology in standardized designs, make component units novel more reliable.
Beneficial effect of the present invention is, can realize that mold presses its position functional unit scale property production, forms the particular demands of electroslag smelting steel different user to the rectangle mold quickly and easily.And embody that mold inner-tube structure intensity is high, furnace life is long, heat exchanger effectiveness is high, save the technical characterstic of electric energy etc.
