Description

A kind of tundish liner vibration moulding device that is heating and curing

The utility model relate to steel-making continuous casting tundish working lining the vibration moulding-system that is heating and curing, the particularly vibration moulding of conticaster tundish dry material working lining-device is heating and curing.

Continuous casting steel machine tundish working lining majority is a refractory coating both at home and abroad, adopts mechanically spraying and artificial smearing method construction; In recent years, begin to test the dry type material as working lining.The construction requirement of dry type material working lining is different with the former: the first, construction equipment will satisfy the vibration needs, and the air that is beneficial in the material is extruded, and makes material have certain density; The second, after vibration, though material has certain density, intensity not, therefore the demoulding at once requires this equipment can the Fast Heating material, material is solidified, and can cool off fast, is beneficial to deviate from the working lining after solidifying.

External at present report about dry type material construction equipment, its basic structure is a kind of coil of strip tube of particular design, working lining thickness and shape realize by adjusting the coil of strip tube, therefore adjust trouble, complex structure, manufacturing, maintenance cost height; Domestic (comprising external) dry type material vibration moulding equipment is fixing form vibrator on the mould tyre sidewall, the density that is easy to cause local material like this inhomogeneous with away from the material density in vibrator zone, to such an extent as to after the heating, working lining may produce localized cracks, influences working lining and uses; Simultaneously, working lining promptly must heat after vibration, and temperature is above 200 ℃, this moment vibrator or pull down, cooling protection is if dismounting certainly will cause the tired lock of loading and unloading, increase labour intensity, if protect, the one, cause this apparatus structure complexity, the 2nd, cause vibrator overheated easily, thereby reduced the service life of vibrator, and even vibrator is scrapped; And the mode of heating of this device is fuel heating (comprising that external heating means also are like this) with coal gas for adopting the burner that is placed in the device top, its deficiency, the one, because the burning of burner is a partial flame, and the shape of tundish also mostly is rectangular obform body, therefore is easy to produce the bigger temperature difference, is unfavorable for the even sclerosis of dry type material, in order to reduce the temperature difference, certainly will to increase the quantity of burner, so not only increase the cost of this device, and increase the difficulty of operation; The 2nd, even in order to guarantee temperature, the temperature difference is less relatively, can be rapidly heated simultaneously, and this device is generally made full-enclosed structure, and the coal gas colorless and odorless, this not only can increase operation easier, and has brought potential safety hazard.

The purpose of this utility model is to change the method for attachment and the mode of heating of existing vibrational structure and impeller, provide a kind of impeller dismounting easy, easy to maintenance, body vibration is even, and heating-up temperature is even, and simple, convenient, safe and reliable vibration moulding-device is heating and curing.

The technical solution of the utility model is, the vibration moulding mechanism of the vibration moulding of the dry type material-device that is heating and curing is made up of top board, base plate and the side plate of vibrator, mould tire, vibrator adopts two kinds of patterns, first kind of vibrator is made up of form vibrator, substrate, the biography girder steel etc. that shakes, earlier form vibrator is fixed on the substrate, on shaking girder steel, biography is provided with a corresponding groove, substrate can insert in this groove, the biography girder steel top that shakes is fixed on the top board of device, the bottom is connected on the base plate of device, the side plate of mould tire is connected with top board, base plate, constitutes an integral body; The vibration moulding mechanism that is made of this kind vibrator can use 2～6 biographies girder steel that shakes, and they are parallel to each other and vertically arrange, place 1 form vibrator and the rotation direction unanimity of these 2～6 form vibrators on the every girder steel; Second kind of vibrator is made up of eccentric block, main shaft, bearing block, shaft coupling, bearing, motor, thermal insulation layer etc., its upper shaft bearing is fixed on the top board of device, the bottom end bearing seat is connected on the base plate of device, the vibration moulding mechanism that is made of this kind impeller can use 2～6 these vibrators of cover, its main-shaft axis is parallel to each other and vertically arranges, and the rotation direction unanimity of main shaft; The device that is heating and curing can be to be the heater of fuel with coal gas, form by gas piping, burner, fire rod, ignition tube, air hose, valve, temperature element and instrument, arrange all gas pipings in bottom of device near mould sidewall plate place, being distributed with diameter on the pipeline is φ 4～14mm, spacing is that the fire hole of 50～500mm is as burner, be accompanied by coal gas burner and arranged fire rod, also has an ignition tube in addition, arrange air hose at the tundish inner chamber first half, the air hose lower end has row's aperture; The device that is heating and curing also can be an electric heater unit, is made up of electrothermal tube, insulation material and control instrument, and electrothermal tube is distributed in base plate and the mould sidewall plate place near device equably, deviates from base plate and mould sidewall plate direction is sealed with insulation material at it; According to the rectangular polymorphic structure of tundish, can be separated into 2～5 relatively independent zones, each zone all is provided with temperature element, controls respectively, is provided with manhole on each regional top board, and keeping to the side is distributed with air-vent.

Advantage of the present utility model is: the mounting or dismounting of the form vibrator of (1) first kind of vibrator only need be inserted and pull out and be got final product, therefore the dismounting maintenance of the vibrating mechanism that is made of this vibrator is simpler than prior art, because form vibrator can be pulled out this device when heating, the electric machine external of second kind of vibrator, therefore the corresponding prolongation in service life of vibrating mechanism also makes the designs simplification of this device simultaneously.(2) the outstanding body vibration of the vibrational structure of this device, be vibration that vibrator produces reach device on, on the lower plate, again by last, the side steel plate that lower steel plate drives whole device produces vibration, thereby the dry type material is vibrated, exhaust, also many vibrators of equidirectional rotation can be superimposed simultaneously, strengthen the exciting force of single unit system, in addition, the exciting force of second kind of vibrator can be adjusted, therefore its vibrating effect is better than existing adhesion type vibrating device far away, thereby the density of the dry type material working lining after the vibration moulding is more even, and the crackle that the baking back produces is few.(3) burner of coal gas mode of heating is simpler than prior art, cost is low, need not maintenance basically.(4) because the gas-fired system lights ignition tube earlier, again by ignition tube firing point lighted torch, feed coal gas at last again by fire rod all fire holes (burner) that ignite, add on this device top board and have manhole, keep to the side and have air-vent, so native system compared with prior art, good operation reliability, safe coefficient height.(5) Electric heating is easy to control temperature, and temperature difference minimum.

To sum up state 5 points, illustrate that this device can be good at satisfying the instructions for use of dry type material working lining, simultaneously because simple in structure, manufacturing cost is lower, except changing the vibrator once in a while, basically need not maintenance (comprising the maintenance of burner), saved the production maintenance cost greatly, improved operating efficiency, this device is simple to operate in addition, and is safe and reliable.
