Casting Babbitt Bearings, Tin-Based Babbitt, Corrosion-Resistant Babbitt

Production of Babbitt metal, bearing alloys, Babbitt bearing shells, support pads, bushings, and liners. We sincerely look forward to cooperating with you to achieve brilliance together. Below, I will briefly discuss some relevant knowledge about the pouring of Babbitt bearing shells for our consumers: 1. Cleaning of alloy bearing shells: Place the bearing shells in a 10%-15% cleaning agent 1 solution to remove rust, then place them in hot water at 80 degrees Celsius to eliminate remaining dirt. After washing, place the bearing shells in hot water at 70 degrees Celsius to rinse off any remaining impurities. After cleaning, avoid touching the inner surface of the bearing shells with your hands. Sometimes, due to prolonged storage after removing old alloys, an oxide layer may form on the surface. Before tinning, perform a 3-minute weak corrosion in cleaning agent 1 solution, then immediately immerse in cleaning agent 2 solution for 2 minutes to neutralize, followed by rinsing with hot water. 2. The adhesion of tin to the bearing shell is better than that of Babbitt metal. After tinning, the Babbitt metal adheres more firmly. The tinning material used is tin or tin alloy, along with a flux. The flux helps remove surface oxides and grease, ensuring a strong bond. Tinning methods include the wiping method and the dipping method. 3. Removing contaminants: Use a blowtorch flame or heating furnace to heat the back of the bearing shell to remove old Babbitt metal. Carefully clean the melted Babbitt metal from the bearing shell with a steel brush, eliminating dirt, rust, and traces of Babbitt metal. Pay special attention to cleaning the oil grooves and dovetail slots. After cleaning, tinning is applied as a base layer before pouring the Babbitt metal solution……
