Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metallurgical furnace and kiln technology, and specifically relates to a device for baking and heating refractory materials. Background Technology
[0002] Refractory materials used in the construction of metallurgical furnaces absorb a certain amount of moisture during production, transportation, and storage. This moisture evaporates rapidly at high temperatures, causing shrinkage and structural changes in the material. Baking and heating gradually removes this moisture, preventing these problems. During baking, specific chemical components within the refractory material react to form more stable compounds, which helps improve its refractory performance and erosion resistance. Simultaneously, the baking process strengthens the bond between material particles, resulting in a more robust overall structure.
[0003] After the refractory lining is completed, the baking process has a decisive impact on the service life of the refractory materials. Uneven temperature distribution during the heating process can lead to cracking and spalling of the refractory materials in high-temperature areas, thus shortening the furnace's service life. Each refractory manufacturer develops a suitable heating regime based on the characteristics of its products to accommodate the required natural gas flow and intensity at different times. During the baking process, ensuring stable and appropriate burner intensity is a prerequisite for protecting the refractory materials from damage. A proper combustion process is crucial for the formation of a stable kiln lining, providing a solid foundation for subsequent operations. Simultaneously, an efficient and stable heating method ensures the reasonable expansion of the elastic structure of the side-blown furnace. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a device for baking and heating refractory materials by rationally configuring combustion guns on the furnace body and controlling the combustion intensity, ensuring that the refractory materials inside the furnace can be heated evenly, achieving efficient baking and heating, thereby improving the service life of the refractory materials and laying a solid foundation for subsequent production and safe operation of the furnace.
[0005] This utility model is achieved through the following technical solution:
[0006] An apparatus for heating refractory materials by baking includes a baking furnace and a combustion lance; the baking furnace includes a furnace cylinder, a furnace body, and a flue; the furnace cylinders are fixedly connected to each other, and the flue is fixedly connected to the furnace body; the baking furnace is provided with a plurality of feed hoppers and a plurality of combustion ports for placing the combustion lance.
[0007] The feed hopper is used to add refractory materials. Both the feed hopper and the combustion port can hold the combustion gun, which is secured with straps or other fasteners to prevent slippage. The combustion port can be designed in multiple positions, such as on the front and back of the furnace hearth and body, as well as the sides, further improving the uniformity and efficiency of baking.
[0008] Further explanation of this utility model: the furnace cylinder is provided with discharge ports at both ends; the inlet is provided with a closed door fixedly connected to the furnace body by a hinge. When the baking furnace is working, the closed door is in the closed state; when the work is finished or when it is necessary to process the slag, the closed door is opened and the slag in the furnace cylinder is processed through the discharge port.
[0009] As a further explanation of this utility model, the furnace body is also provided with an observation port for observing the internal conditions of the baking oven.
[0010] To further illustrate this invention, an oxygen inlet is also provided next to the combustion port. By providing an oxygen inlet, combustion efficiency can be improved; additionally, an oxygen-enriched air device can be placed to further enhance combustion efficiency.
[0011] As a further description of this utility model, a support frame is provided outside the combustion port for placing the combustion gun.
[0012] Further explanation of this utility model: the support frame is provided with a fixing component and screw holes; the fixing component includes a fixing plate and fixing screws that match the screw holes. Through the cooperation of the fixing screws and screw holes, the burner is pressed under the fixing plate, thus fixing the burner and improving production safety.
[0013] To further illustrate this invention, the support frame is fixed to the furnace body at an angle. This allows the burner to be inserted obliquely into the furnace, with the burner nozzle close to the bottom of the furnace, thus improving the efficiency of baking and heating.
[0014] The beneficial effects of this utility model are:
[0015] This invention uses a combustion gun to bake and heat the refractory material in the furnace hearth. By using a support frame and oxygen inlet to enhance the combustion efficiency and intensity of natural gas, it achieves a reasonable, safe, and efficient baking and heating process. This ensures that the refractory material in the furnace is heated evenly, achieving efficient baking and heating, thereby improving the service life of the refractory material and laying a solid foundation for subsequent production and the safe operation of the furnace.
