Description

The invention relates to furnaces designed for ftairpeBa products, in particular for paiBHOiMep-heating of large-sized products, such as firing of the EM in the left coating, and can be used in non-chemical and chemical engineering in metallurgical and other companies in other industries. .thinking. It is known to be used for burning enamel; a coating, 1 on "Esenno: on a product, containing a calcining tube with a tube in it and a device for transport and articles. The transporting device is made in the form of a mobile support on which the product is loaded, 1. The disadvantage of this "destruction" is the introduction of a cold support into the hot zone of the working space of the furnace and its presence in the furnace during the heating of the product. It is also known to heat the bed, containing the roasting chamber with an opening in the hearth and the loading / unloading mechanism, made in the form of a mobile support 2. The heated product is placed on the support, which is at that moment outside the furnace, after which the product is transported to the furnace, along with the support, and in the process of heating the product, the support is located in the working space of the furnace. The known furnace for heat treatment of products, containing successively three chambers, communicating with each other, moreover, two chambers 3 are simultaneously movable and in working position at the same time overlap. The purpose of the invention is to improve the quality of heat treatment of heated products. This is achieved by the fact that the middle section of the hearth is made with the possibility of horizontal movement and is kinematically connected with the loading-unloading mechanism and a hydraulic lock is placed between the sections of the hearth. On the fit. l depicts a furnace during the heat treatment period; in fig. 2 is a section along A-A in FIG. one; in fig. 3 - furnace during the loading (discharge; on fig. 4 is a section along BB in Fig. 3. The furnace contains a firing 1 chamber, the working space of which is connected to the working space of the isometric 2 chambers through the overlapping window 3 located in the firing wall chambers. Under the calcining chamber 4 is made sectional. In the opening 5 there is a middle section 6, made movable and connected kinematically with the lined frame 7 of the lifting mobile device 8. with the help of a hinge rod 9.

On (hearth 4 Mounts 10 are installed for the mouth of the stretched product 11. On the loading-unloading side, the flow is onabzhen lined with the G2 flap on the inside. To move the middle section I (the lined frame 7 is provided respectively with stationary 16 (with a fixed level ) and 14 roller lifting tracks. Stationary roller tracks are located under the firing and isothermal chambers.

Lifting roller roads; the ki are located (UNDER the calcining chamber and the shaft of it and, in combination with the lined frame 7, are a lifting-mobile device 8 of the loading-unloading mechanism.

A pin rail 15 is fixed on the lower part of the movable middle section, the interaction of which with the pinwheel 16 of the movement mechanism 17 of the section ensures simultaneous movement of the kinematics connected between the middle section of the hearth and the frame 7 of the lifting-mobile device 8. For fixing the product on the lined frame 7 volumes 18. Hydraulic gates 19 are installed between the hearth sections, which provides sealing of the furnace. The lifting of the frame 7 is carried out with the help of a hydraulic cylinder 20.

The furnace works as follows.

The product with applied enamel .. coating is installed on the frame of the lifting-mobile device with the help of and: well-known lifting and transport means. With the ram of the hydraulic cylinder, the lined frame is lifted to the upper position by switching on the mechanism (moving the middle hearth section moves to the isothermal chamber, which prevents the bottom section from cooling at the time of loading and unloading the product.

Simultaneously with the movement of the hearth section into the isothermal chamber, the lined frame of the lifting-movable device with the product moves into the swaging chamber. Using PIdrodili D1ra, the lined frame is lowered, 1 when this product is placed on the stationary apora, after which the frame is rolled out of the kiln chamber by the movement mechanism, and the opening is blocked by the movable hearth section. The damper is lowered. To unload the kiln chamber, the flap is raised, then the movable section is moved into an isothermal chamber by turning on the movement mechanism, which ensures that the lined frame is in the lower position, e Objigger chamber. With the help of a hydraulic cylinder, a lined frame (1POD product, removed it) three of these are from stationary supports, after which the section is moved from the isothermal chamber to the firing, while simultaneously rolling out the lined frame from the burning chamber. Then lower the damper, and the lined frame with the product Strongly cylinder is moved to the lower position.
