Description
Technical Field
The utility model mainly relates to a platform truck heating furnace for hot-working enterprise, especially use frequent high temperature platform truck heating furnace, more specifically relate to a platform truck that heat resistance is good.
Background
The durable material structure of platform truck includes: the heat insulating layer, the working layer and the like are mainly used for supporting workpieces of the trolley type heating furnace, so that the sufficient bearing capacity is ensured, and the heat loss of the furnace bottom is reduced. The heat insulating layer is arranged at the lowest part and has good heat resistance. The heat insulation layer is arranged in the middle, so that the heat resistance is good, the temperature resistance is good, and the support strength is good. The working layer is arranged on the uppermost surface and contacts with a high-temperature area of the hearth, but the working layer has low thermal resistance, high temperature resistance, friction resistance and high supporting strength. The working layer refractory material is high-strength slag-resistant castable, the castable is poured in blocks, expansion gaps are arranged among blocks, and the refractory material has general rapid cooling and rapid heating resistance. Due to long-term impact of high and low temperature, expansion joints are enlarged, iron scales are filled in the joints, the expansion effect is lost, and in addition, heavy pressure of workpieces causes cracking and abrasion of a working layer refractory material, so that the energy consumption is high, the surface is uneven, heating workpieces cannot be normally placed on the working layer refractory material, a thermal insulation layer and a thermal insulation layer are damaged in serious cases, and the maintenance is required to be carried out in less than two years. And when the maintenance is carried out, the whole working layer is required to be replaced, the time consumption is long, the cost is high, and the influence on the productivity is large.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a not enough to prior art, the utility model discloses a platform truck that heat resistance is good, aim at solves because long-term high microthermal impact, and the expansion joint grow, and the seam is filled with the iron scale, loses the dilatancy, and the repression of work piece in addition, the resistant material of working layer ftractures, wearing and tearing, and then leads to the energy consumption height, surface unevenness, heating workpiece can not normally put on, leads to the problem that insulating layer and heat insulation layer damaged when serious.
In order to achieve the expected purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a platform truck that heat resistance is good, includes heat insulation layer, insulating layer, working layer, and the heat insulation layer is at the bottom, and the insulating layer is in the centre, and the working layer is at the top, its characterized in that: the working layer comprises a working layer periphery and a working layer middle structure, the working layer periphery is poured by wear-resistant materials in blocks, an expansion joint is arranged on the working layer periphery, and the working layer middle structure is made of heat-resistant powdery materials.
Furthermore, the periphery of the working layer is formed by pouring high-strength steel fiber wear-resistant pouring materials.
Furthermore, the periphery of the working layer is poured in blocks, and expansion gaps are arranged among the blocks.
Furthermore, the structure of the middle part of the working layer adopts hot dry powder ramming material.
Has the advantages that: newly designed trolley refractory structure: the service life is prolonged, the maintenance cost is reduced, and the utilization rate of equipment is improved.
Drawings
Fig. 1 is a structural diagram of the present invention.
Wherein: 1. the periphery of the working layer 2, the middle structure of the working layer 3, the heat insulation layer 4 and the heat insulation layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; may be a mechanical connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
As shown in fig. 1, a bogie having good heat resistance includes a heat insulating layer 4, a heat insulating layer 3, and a working layer. The heat insulation layer 4 is arranged at the bottom and has good heat resistance but no high temperature resistance, and the heat insulation layer 3 is arranged in the middle and has good heat resistance, good temperature resistance and good support strength. The working layer is arranged on the uppermost surface and contacts with a high-temperature area of the hearth, and the hearth has low thermal resistance, high temperature resistance, friction resistance and high supporting strength. The working layer comprises a working layer periphery 1 and a working layer middle structure 2, wherein the working layer periphery is formed by pouring wear-resistant materials in a blocking mode, and specifically, the working layer periphery 1 is formed by pouring high-strength steel fiber wear-resistant pouring materials. The peripheral expansion joint that is equipped with of working layer, it is concrete, 1 piecemeal concretings in working layer periphery are equipped with the expansion joint between the piecemeal concreting, and this part is able to bear or endure material wearability, the older pouring material of intensity increase a lot, can play the effect of fixed, the middle resistant material of protection. The middle structure 2 of the working layer adopts a hot dry powder ramming material.
The specific working principle is as follows: during construction, the refractory material at the periphery 1 of the working layer is constructed firstly, the refractory material of the heat insulation layer 4 and the refractory material of the heat insulation layer 3 are constructed after the form is removed, and the middle structure 2 of the working layer is constructed finally. The working layer middle structure 2 adopts hot dry powder ramming mass, the thermal expansion coefficient of the material is very low, the rapid cooling and rapid heating resistance is very good, the strength and the wear resistance of the hot dry powder ramming mass after being baked are greatly increased compared with those of the old trolley working layer, the hot dry powder ramming mass is not easy to crack, and iron oxide scales cannot enter the hot dry powder ramming mass. When the device is used, a workpiece to be processed is directly placed on the working layer to be heated. Even if the surface of the working layer middle structure 2 is abraded after being used for a period of time, only the surface sundries need to be cleaned, the hot dry powder ramming mass is paved again, and after the hot dry powder ramming mass is simply baked, new and old materials can be tightly combined to achieve the original effect.
To sum up, the utility model discloses reach anticipated purpose.
