Embodiment 1

[0059] combine Figure 1-Figure 6 , the test method of a kind of heating furnace test device of the present embodiment comprises the following steps:

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

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

Embodiment 2

[0075] The heating furnace test device in the test method of a heating furnace test device in this embodiment has basically the same structure 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, a black body material is applied in the furnace 100, and a deflector 120 is installed inside the furnace 100, and the deflector 120 is used as a dividing line to divide the interior of the furnace 100 into a heating area and an exhaust area. like figure 1 As shown, through the setting of the guide plate 120, the hot air flow can evenly pass through the upper and lower surfaces of the billet 200 in the furnace and heat it, which is in line with the actual working conditions of production. The heating area adopts the bracket 130 to support the steel billet 200, and the cooling water is used to circulate and cool the bracket 130, which e...

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, in particular to a testing method for a heating furnace testing device. Background technique [0002] In the hot rolling process of the iron and steel metallurgy industry, in order to ensure the rolling requirements, the steel 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 lower than 30 ° C. The heating system of the heating furnace determines the furnace temperature and 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 heating system on the billet temperature field has always been the focus of attention. Existing research is mainly done from two aspects of CFD simulation and black box testing. [0003...
