Description
Technical field
The utility model relates to a kind of device that crystallizer coolant-temperature gage is stable of guaranteeing in continuous casting production process, belongs to continuous casting installation for casting technical field.
Background technology
Heat flow density also claims heat flux, refers in the unit interval by the heat on object unit cross-sectional area.For continuous casting is produced, crystallizer heat flow density (hereinafter referred to as: heat flow density) refer to the heat that unit interval interior crystallizer cooling water is taken away from the casting billet surface unit are by copper coin, its stability can affect the uniformity of casting blank shell thickness in crystallizer, thus affect the stability of cc billet surface quality and production, therefore this index is usually used to weigh the quality of casting billet surface cooling effect and the height of continuous casting production control level.When the stability of heat flow density is better, that is: when the absolute value ratio of front and back moment heat flow density difference is no more than 5%, cc billet surface quality is better, can not produce surface longitudinal crack; And when the less stable of heat flow density, that is: when the absolute value of front and back moment heat flow density difference is more than 300J/ ㎡/s, cc billet surface quality and even production will be greatly affected, or serious longitudinal crack defect appears in casting billet surface that is:, thus affect final product quality, there is bleed-out accident, affect the stable operation of whole continuous casting working procedure.Therefore, be one of most important link in continuous casting manufacturing technique process to the stability contorting of crystallizer heat flow density.
Usually, the factor affecting crystallizer heat flow density stability mainly comprises: pulling rate, molten steel composition, cast temperature, covering slag performance, cooling water flow, crystallizer copper plate thickness, copper plate of crystallizer sink size, conical degree of crystallizer, length of mould, copper coin surface appearance, crystallizer inflow temperature, crystallizer cooling water quality.Therefore, if can adopt an effective measure, stablize above-mentioned factor, just effectively can improve the stability of crystallizer heat flow density.
In recent years, along with the lifting of equipment performance and technology controlling and process level, effective control is all obtained with most of factor of crystallizer heat flow density, as: for pulling rate, molten steel composition, cast temperature, covering slag performance factor, production scene effectively improves its stability by lifting process level of control; And for cooling water flow, crystallizer copper plate thickness, copper plate of crystallizer sink size, conical degree of crystallizer, length of mould, copper coin surface appearance, crystallizer cooling water quality factor, production scene then efficiently solves the stability of above-mentioned factor by the automatic control accuracy of the machining accuracy of raising equipment, the accuracy of detection of instrument and raising automatic equipment.Therefore, if can guarantee that crystallizer cooling water temperature is stabilized in a rational temperature range, the stable of crystallizer hot-fluid just finally can be realized.
According to technological requirement, usually need by crystallizer cooling water temperature stability contorting within the scope of 30 ~ 38 DEG C, can guarantee that within the scope of this casting billet surface does not produce the stable operation of total crackle and continuous casting production.But the difficulty realizing this water temperature control range is at present comparatively large, and its main cause is that it can be subject to the double influence in on-the-spot actual condition and season usually.Concrete reason is: because crystallizer cooling water recirculation system (being called for short: the circulatory system) belongs to inner loop mode, namely cooling water flows in a closed pipeline, while by copper plate of crystallizer cooling casting billet surface, cooling water also can cause the rising gradually of its temperature because absorbing a large amount of heats, when cooling water temperature exceedes the scope of requirement, will produce continuous casting and impact.In addition, water temperature rising can cause cooling water to evaporate in a large number, thus causes the minimizing of total Water, and then affects cooling water flow, finally can cause the significantly reduction of copper plate of crystallizer working life.Therefore, for solving the problem, production scene can according to actual condition, irregularly in crystallizer cooling water recirculation system, adds a certain amount of cooling water.Water temperature due to the cooling water newly added is subject to the impact in season, larger difference is there is with the cooler-water temperature in the former circulatory system, therefore after adding cooling water, in crystallizer cooling water recirculation system can there is larger fluctuation compared with previous moment in the temperature of cooling water, and then cause crystallizer heat flow density appearance fluctuation by a relatively large margin, thus very large impact is caused on cc billet surface quality and rhythm of production.
Traditional solution reduces the water yield that once adds crystallizer cooling water recirculation system and accelerates cooling water circulation speed, thus reduce fluctuating temperature to greatest extent.But this mode realizes to sacrifice the copper plate of crystallizer life-span and to affect whole rhythm of production, mode of operation is comparatively loaded down with trivial details simultaneously, and comparatively large by the influence degree of manual operation, the effect therefore realizing crystallizer cooling water temperature stable by this kind of mode is unsatisfactory.
At present, along with the development of technology, some crystallizer cooler-water temperature stabilization techniques are developed, and these methods concentrate on the direction using heat transferring medium cooling water to be carried out to cooling processing, carry out forced heat-exchanging as adopted hot water, cold water, liquid nitrogen etc. to crystallizer cooling water.Although these methods can play a role to the water temperature stability of crystallizer, the shortcoming existed is mainly:
1, control mode is comparatively extensive, cannot control comparatively accurately the temperature of crystallizer cooling water;
2, need to arrange special external refrigeration device, because crystallizer cooling water recirculation system is larger, therefore the volume of cooling device also must be comparatively large, and the floor space of needs also will be larger;
3, need to make special heat transferring medium, and cannot use on-the-spot existing heat transferring medium, therefore operating cost is higher;
4, owing to being cool in cooling water pipeline outside, the impact of therefore being expanded with heat and contract with cold, pipeline is as easy as rolling off a log to break, and causes the damage of equipment, thus has influence on the normal operation of continuous casting production.
Therefore, up to the present, for the stable not effective especially and rational device of maintenance crystallizer cooler-water temperature, how keeping crystallizer cooler-water temperature to stablize becomes the key issue of stabilizing and increasing affecting slab quality, is not effectively solved so far.Adopt an effective measure and solve the reasonable and stable problem of crystallizer water temperature in continuous casting production process, by guaranteeing that vital effect is played in the stable operation of slab quality and continuous casting production.
