Detailed Description
The present invention will be further described with reference to the following detailed description of the embodiments.
The device for testing the alloy material comprises a control needle 1, a lead melting funnel 2, an electric heating tube 3, a heat insulation material 4 and a body 5, wherein the lead melting funnel 2 is arranged on the body 5, the electric heating tube is arranged around the lead melting funnel 2, the heat insulation material 4 for sealing the electric heating tube 3 and the heat insulation material 4 are preferably arranged on the body 5, and the control needle 1 is detachably arranged at the bottom of an inner cavity of the lead melting funnel 2. The material of the lead melting funnel 2 is required to be smooth ball-milling cast iron material or 45 steel, the bottom of the funnel is designed for controlling the flow rate of lead liquid, the diameter of the funnel is required to be 3-8mm, and the length of the funnel is required to be 30-100 mm. The control needle 1 is made of high-temperature-resistant metal material, such as copper, is matched with the bottom of the funnel for use, is fixed during heating to prevent the lead liquid from flowing out, and is taken out after the temperature meets the requirement, so that the effect of controlling the quality of the lead liquid is achieved; the electric heating tube 3 is of a spiral structure and is heated in an upward and upward outlet mode; the heat insulating material 4 is used in cooperation with an electric heating tube.
During specific operation, step 1, heating an electric heating pipe, and preheating a lead melting funnel to 370 and 420 ℃; step 2, the control needle is positively fixed at the bottom of the inner cavity of the lead melting funnel to prevent a gap from existing and prevent subsequent lead liquid from flowing out; step 3, injecting lead liquid into a cavity of the lead melting funnel; and 4, taking out the metal control needle after the temperature reaches the testing temperature, and simultaneously recording the time for the lead liquid to completely flow out of the funnel. The fluidity of the alloy is judged according to the time. The method can accurately compare the fluidity of various lead alloy materials and judge the casting performance of the lead alloy materials.
At least 4 temperatures of 370 ℃, 420 ℃, 470 ℃, 520 ℃ and 680 ℃ are tested for each alloy material, wherein the alloy material is used for evaluating the lead slag content of the alloy material at low temperature, and the fluidity is poor when the slag content is high; and (4) evaluating the flow property of the alloy material during casting at high temperature, and comparing the forming rate of the grid alloy. In addition, the liquid level of the lead liquid is ensured to be consistent during each test.
In addition, in the step 4, after the temperature reaches the testing temperature, the metal control needle can be taken out after the temperature is kept for a period of time, and meanwhile, the time for the lead liquid to completely flow out of the funnel is recorded. The heat preservation time is controlled by the electric heating tube 3, the fluidity of the alloy material after different heat preservation times can be tested, and the content of the lead slag of the alloy material is different in different heat preservation times.
The lead alloy material comprises positive lead-calcium alloy, positive lead-antimony alloy, lead used in ball milling, electrolytic lead, lead alloy used in cast welding and the like.
The device can be fine, the mobility of swift test lead alloy material, provides convenient for the formulation of screening and the standard of follow-up lead alloy material.
