Important factors in determining the quality of stainless steel precision castings



Important factors in determining the quality of stainless steel precision castings
Temperature is an important factor in determining the quality of stainless steel precision castings. Let's take a look at the important factors that determine the quality of stainless steel precision castings.
First, the melting furnace temperature is unstable, so a temperature difference will occur during the pouring process, which has a great impact on the accuracy of the measurement. Temperature control in precision casting is to use these temperature data to find a temperature range that guarantees the quality of the casting.
Second, the signal processing capability of the measurement device itself is not strong. Since each analog to digital or digital-to-analog conversion between the measurement instrument and the control device causes an error, a wide temperature simulation range may result in a decrease in measurement accuracy.
Third, if a non-standard melting technique is used in precision casting, it will also have a certain impact on temperature measurement. If the high vapor pressure element transitions to boiling, the surface of the molten pool is disturbed or forms a reaction product, this will inevitably cause errors in the conventional pyrometer.

                Ten things that must be paid attention to in precision casting! 1. Unblock all obstacles to the channel and site. 2. Check if the ladle is dry, whether the bottom of the bag, the ear, the bag and the end are safe and reliable, and whether the rotation is flexible. Do not use dry Iron ladle. 3, all tools in contact with molten iron, must be preheated to 500 degrees Celsius before use, otherwise it should not be used. 4, the ladle should not exceed 80% of the volume, the ladle should be smooth and slow, keep the steps to prevent the overflow of molten iron. Cast iron 5, before the crane crane should check the iron of the hook, the chain is reliable, the chain is not allowed to knot, there is a person responsible for tracking the iron in the water There must be no staff on the line. 6. Strictly implement the "six will not fall": (1) The temperature of molten iron is not enough; (2) The molten iron grade is...

                    Understand the importance of defects in precision castings     In actual production, it is often necessary to analyze casting defects, the purpose of which is to find out the cause of the defects so that measures can be taken to prevent them. For precision casting designers, understanding product defects and causes can help to properly design the casting structure and combine the actual conditions of the casting production to properly formulate the technical requirements. There are many defects in precision castings , and the defects and causes are very complicated. Sometimes, defects caused by many different reasons appear on the same casting, or the same reason may cause various defects when the production conditions are different. Whether a defective casting with defects is classified as waste must be determined according to the use and requirements of the casting and the location and severi...

                                                                   Factors affecting the surface roughness of stainless steel castings Surface roughness is another major quality indicator for stainless steel castings , generally less than 3.2 μm, between 0.8 and 3.2 μm. There are many factors affecting the surface roughness of castings, such as the pressure type, the surface quality of the investment and stainless steel, the casting process, the type of alloy and other factors. (1) Profile and investment surface quality. The surface roughness of the investment mold is the most important part affecting the surface roughness of the casting, and it is related to the surface quality of the molding, the compression molding method and the pressing process parameters. (2) Stainless steel surface quality. Stainless stee...
