Embodiment 1

[0059] Combine Figure 1-Figure 6 , The test method of a heating furnace test device in this embodiment includes the following steps:

[0060] Step 1: Use mechanical equipment such as forklifts or hoisting to transport the billet 200 to the bracket 130 inside the furnace 100 of the heating furnace;

[0061] Step 2: Drill holes at different depths inside the billet 200, fix the billet thermocouple 201 in the corresponding temperature measuring hole, and then lead the billet thermocouple 201 to the heating furnace through the thermocouple lead wire 710 through the magnetic bead Outside, and closed the furnace hearth 100. Specifically, such as Figure 4 As shown, there are three types of temperature measurement points inside the billet 200. From the upper surface of the billet 200 downwards are the upper surface temperature measurement point 210, the center temperature measurement point 220, and the lower surface temperature measurement point 230, which are used to detect the upper s...

Embodiment 2

[0075] The structure of the heating furnace test device in the test method of a heating furnace test device of this embodiment is basically the same as that of Embodiment 1. Furthermore, the interior of the furnace 100 in this embodiment is built with refractory materials. Specifically, this In the embodiment, in order to increase the radiation effect, black body material is applied in the furnace 100, and a baffle 120 is arranged inside the furnace 100. The baffle 120 is used as a dividing line to divide the interior of the furnace 100 into a heating area and an exhaust area. Such as figure 1 As shown, through the arrangement of the baffle 120, the hot air flow can uniformly pass through the upper and lower surfaces of the billet 200 in the furnace and heat it, which conforms to the actual production conditions. In the heating area, the bracket 130 is used to support the billet 200, and the cooling water is used to circulate the bracket 130 to ensure the support stability of th...

Abstract

The invention discloses a test method for a heating furnace test device, and belongs to the technical field of heating furnaces. The test method comprises the following steps: I, transferring steel billets onto a bracket in a furnace hearth; II, punching inside the steel billets, and fixing a steel billet thermocouple in a measuring hole; III, connecting a thermocouple lead-out wire to a signal acquisition module; IV, switching on an air blower; V, switching on a power supply and a temperature controller for an air heating section I, an air heating section II, an air heating section III and anair heating section IV to sequentially accomplish each working condition of furnace body pre-heating simulation, pre-heating section simulation, heating section I simulation, heating section II simulation and uniform-heating section. The test method aims to overcome the defects that existing steel billet heating schedule is uncertain in research test time, is not high in precision of measured results, and the like, can research steel billet heating schedule, further can improve measuring precision, and grasps test time.

Description

Technical field [0001] The invention relates to the technical field of heating furnaces, and more specifically, to a test method of a heating furnace test device. Background technique [0002] In the hot rolling process of the iron and steel metallurgical industry, in order to ensure the rolling requirements, the billet needs to complete the secondary heating process in the heating furnace. The heating target temperature is generally about 1200°C, and the cross-sectional temperature difference is less than 30°C. The heating system of the heating furnace determines the tapping temperature and the cross-sectional temperature difference of the billet, and the temperature system is determined by the furnace temperature distribution and heating time. Therefore, the research on the influence of the heating system on the temperature field of the billet has always been the focus of attention. The existing research is mainly done from two aspects: CFD simulation and black box testing. [...
