• What is the correct way to replace the main frame seat liner in cone crusher?

  May 29, 2025

  In the use of cone crushers, wear parts often need to be replaced due to damage. Today we will introduce how to correctly replace the stone crusher parts name main frame seat liner.   Many customers report that the parts of crusher machine main frame seat liner is difficult to weld on the main frame. This is mainly because they do not master the welding process. Pay attention to the following points:   1. Thoroughly clean the welding position.   2. Heat the main frame to 100 degrees before welding, and the cone crusher parts name main frame seat liner also needs to be baked to about 40-50 degrees.   3. Weld from the middle to both sides.   4. Keep warm for 1 hour after welding.   In China, the welding rod we usually use is T237 3.2mm. The following are the main parameters of the welding rod.   Aluminum-manganese bronze is a copper alloy electrode with a welding core and a low-hydrogen coating. The deposited metal contains alloys such as Al 6.5-10%, Mn≤2.0%, Cu＜90%, etc., with excellent wear resistance and corrosion resistance. A DC power supply is used, and the electrode is connected to the positive electrode. It is used for welding aluminum bronze and other copper alloys, copper alloys and steel, and repairing cast iron. Such as welding of various chemical machinery, seawater radiators, valves, surfacing welding of water pumps, cylinders, etc. and repairing of ship propellers. Before welding, the electrode needs to be baked at about 200℃ for 1h. The moisture, oil, oxides and other impurities on the surface of the weldment must be cleaned. For welding aluminum bronze and surfacing welding of carbon steel, thin parts do not need to be preheated, and thick parts must be preheated at about 200℃.

• What is the difference between 45# steel and Q235 steel?

  Jun 05, 2025

  Bolts and nuts are available in various materials, each with distinct properties and applications. ONA always use 35#/45# steel, which 8.8 grade. If customers need 10.9 grade, we can customized too. Some customers ask what's the difference of material 35#/45# steel and Q235, Q335?   Difference between 35#/45# steel and Q235 steel?  Characteristic 35#/45# steel (medium carbon steel) Q235 steel (low carbon steel) Carbon Content The carbon content of 35# steel is about 0.35%, and the carbon content of 45# steel is about 0.45%. Carbon content less than 0.22% Strength High strength, tensile strength ≥600MPa, yield strength ≥355MPa The strength is relatively low, with a tensile strength of 370-500MPa and a yield strength of about 235MPa Hardness The hardness is relatively high. Before heat treatment, the hardness is lower than HRC28. After quenching and tempering, the hardness can reach HRC22-HRC33 Low hardness, less than HRC20 Welding Performance Poor welding performance, prone to cracks Good welding performance, suitable for welding structural parts Processing Performance The processing is difficult and suitable for manufacturing high-strength mechanical parts. Easy to process, suitable for cold working and welding operations Heat Treatment Frequent heat treatments such as quenching and tempering to improve hardness and wear resistance Generally no heat treatment is performed and the heat treatment effect is not obvious Usage Used to manufacture high-strength mechanical parts such as shafts, gears, couplings, etc. Used to manufacture welded structural parts such as steel structures, brackets, fences, platforms, etc.   Difference between Q235 steel and Q345 steel?  Characteristic Q235 Steel Q345 Steel Carbon Content Carbon content less than 0.22% Carbon content <0.20% Strength Yield strength 235MPa, tensile strength 370-500MPa Yield strength 345MPa, tensile strength ≥470MPa Hardness Lower hardness, better plasticity Higher hardness and high strength Welding Performance Good welding performance, suitable for welding structural parts The welding performance is better, but not as good as Q235 Processing Performance Easy to process, suitable for cold working and welding operations Good processing properties, but higher strength Usage Used for general structural parts, buildings, bridges, etc. Used for structural parts and machinery manufacturing that require higher strength Price Lower price The price is slightly higher, but it saves 15%-20% of steel compared to Q235   ONA is also processed stone crusher part according to the original factory drawings and materials, and the crusher wear part product quality is strictly controlled. Don't worry, if other materials and requirements are needed, we will provide professional suggestions, and after the customer's consideration, we will produce according to the customer's requirements.
