Abstract
The invention provides a thermal insulation construction and method used for a steel slag thermal smouldering device. The thermal insulation construction provided by the invention is characterized in that a thermal insulation layer of a thermal insulation device is internally provided with a constructional reinforcement and is filled with thermal insulation castable, so as to reduce the temperature of a concrete construction and protect the concrete construction. Compared with the prior art, the thermal insulation construction disclosed by the invention can be used for effectively and greatly reducing the working temperature of the concrete construction, improving the durability of concrete, enabling the thermal insulation castable to achieve better integrity, reducing the maintenance frequency and improving the use security.
Description
Technical field
The present invention relates to the metallurgy industry slag and handle the thermal insulation construction field of hot vexed process heat disintegrating device.
Background technology
Hot disintegrating device is that slag is handled the equipment that adopts when hot vexed technology is carried out work, and generally, the structure of hot disintegrating device side is respectively slag, steel billet, thermofin, concrete side walls, soil from inside to outside.Because hot vexed process using is the mode that molten steel slag (temperature is more than 1400 degrees centigrade) directly enters hot disintegrating device, and steel billet directly contacts the thermofin thinner thickness between molten steel slag, steel billet and the concrete, so cause the temperature of concrete side walls and base plate can be than higher.
It is heat insulation heat insulation with slag that the heat insulation mode that adopts mainly contains air at present, the advantage of this dual mode is that cost is lower, but it is undesirable that shortcoming is effect of heat insulation, according to field monitoring, this dual mode may cause the concrete inner wall top temperature to reach about 200 degrees centigrade and 150 degrees centigrade, such state of temperature can produce detrimentally affect to the concrete main body durability of structures, thereby causes producing when ordinary production unsafe factor.
Summary of the invention
The object of the present invention is to provide a kind of thermal insulation construction and method, be used for the heat insulation of hot disintegrating device, playing effect of heat insulation preferably, thereby effectively reduce the temperature of hot disintegrating device concrete structure self, and then the work-ing life of prolongation hot disintegrating device, and strengthen security.
For achieving the above object, the present invention is achieved through the following technical solutions: a kind of thermal insulation construction for steel slag hot disintegrating device, and have and form rectangle or round-shaped sidewall, described sidewall is divided into inside and outside multilayered structure, it is characterized in that:
Described thermal insulation construction comprises: sidewall skin, thermofin and side wall inner layer; It is heat insulation that described thermofin adopts indefinite form heat insulating casting material 2 to carry out.
Described sidewall is outer for being arranged on the concrete 4 outside the sidewall, and described side wall inner layer is the steel billet 1 that is arranged on inside sidewalls.
Arrange reinforced mesh in the thermofin between hot disintegrating device steel billet and concrete, and stuffed heat insulated mould material.
Described thermofin has certain thickness space, described heat insulating casting material 2 internal layout reinforced mesh 3.
Described thermofin gap thickness is 170mm～200mm.
Compared with prior art, the invention has the beneficial effects as follows:
According to field monitoring, by adopting technology of the present invention, the temperature of hot disintegrating device concrete structure inwall reduces comparatively obvious, thermal spike is stabilized in about 90 degrees centigrade, reduce by 60 ~ 110 degrees centigrade than prior art, simultaneously because comparatively abominable (the high temperature cold cycle of Working environment, and there is water to exist), therefore, pay attention to taking into account the weather resistance of effect of heat insulation and material in the selection of lagging material, indexs such as intensity, lagging material also possesses better resists the working conditions that high temperature has water, and because the existence of reinforced mesh is arranged, effectively strengthened the globality of heat insulating casting material, improved its weather resistance, thereby guaranteed carrying out smoothly for a long time of production, more favourable to the safety of hot disintegrating device.

Fig. 1 is hot disintegrating device thermofin structure and method synoptic diagram.
Among the figure: 1-hot disintegrating device steel billet, 2-heat insulating casting material, 3-reinforced mesh, 4-concrete side walls
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing.
A kind of thermal insulation construction for steel slag hot disintegrating device has and forms rectangle or round-shaped sidewall, and described sidewall is divided into inside and outside multilayered structure, it is characterized in that: described thermal insulation construction comprises: sidewall skin, thermofin and side wall inner layer; It is heat insulation that described thermofin adopts indefinite form heat insulating casting material 2 to carry out.
Described sidewall is outer for being arranged on the concrete 4 outside the sidewall, and described side wall inner layer is the steel billet 1 that is arranged on inside sidewalls.
Described thermofin has certain thickness space, described heat insulating casting material 2 internal layout reinforced mesh 3.
Described thermofin gap thickness is 170mm～200mm.
As shown in Figure 1, after concrete side walls 4 is built, at first carry out construction and the installation of reinforced mesh 3, after treating that reinforced mesh 3 installs, carry out the installation of hot disintegrating device steel billet 1, last is template with the inwall of concrete side walls 4 and the outer wall of hot disintegrating device steel billet 1, carries out building of heat insulating casting material 2 in thermofin, and material feeding moulding to be poured can enter normal operational phase after reaching intensity.
Wherein, the significant parameter index of heat insulating casting material 2 is as shown in table 1:
