The five elements of controlling project quality:
Construction personnel quality, machinery and equipment, raw materials, construction methods and construction environment. The quality control of raw materials is an important part of ensuring project quality. Therefore, the control of the quality of construction raw materials must not be careless.
The main materials used in the project (such as steel plates, fittings, appliances and equipment) must have Chinese quality certification documents. Specifications, models, and performance test reports should meet national technical standards or design requirements. When entering the site, inspection and acceptance shall be done and checked and confirmed by the supervision engineer.
Check whether the physical and mechanical properties of the Steel Plate meet the design requirements.
Electrode selection and storage:
“Section 4.2.6 of the Code for the Acceptance of Construction Quality of Buildings for Water Supply and Drainage and Heating” GB50242-2002 Article 4.2.6 stipulates: The external dimensions of the weld shall conform to the requirements of the drawings and process documents, and the height of the weld shall not be lower than the surface of the base metal. Welds and parent metal Should be a smooth transition. The surface of the weld and heat-affected zone should be free from cracks, fusion, incomplete penetration, inclusions, craters, and porosity.
First, the chemical composition and mechanical strength of the welding rod should be the same as those of the parent metal. In order to ensure the safety of the welding workpiece, under the premise of meeting the safety conditions, consider the working conditions and the craftsmanship.
Do not use wet electrodes during welding. If the workpiece is welded with a damp electrode, the workability of the workpiece will be deteriorated, and the arc will be unstable, the spatter will increase, and the weld will be prone to defects such as pores and cracks. Therefore, the electrode is generally placed in an oven before drying, placed in a drying cylinder or a heat-insulating tube, ready for use.

Casting Materials


Casting Material has the good resistance to high temperature and abrasion, combined with convenient production, moderate cost, and is known as one of the most excellent abrasive wear resistant materials.

Casting Wear Part is kind of Bi-Metal Casting Materials, which has the good resistance to high temperature and abrasion, combined with convenient production, moderate cost, and is known as one of the most excellent abrasive wear resistant materials.

Casting Materials is with great hardness and smooth surface. The Casting Wear Liners can be well anti-abrasion without changing the shape. HP provides the various Casting Wear Parts including Hammer, Wear Point, Fan Blades, Dredge Teeth & Adapter, Crusher Teeth, etc...which are widely applied to mining site, cement industry, quarry site, steel mill, coal site and anywhere need to solve wear problem.



HP Wear Resistant Group offers the various casting material for the customers who need to solve wear problem like cement plant, steel mill, mining site, etc... The challenging environments inherent in cement production dictate durable long lasting parts are used within the mills. Our experienced engineering and sales departments understand the requirement of supplying to our cement customers high quality parts that are long lasting and reduce downtime.

We supply a broad range of ferrous metals for cement production wear parts that provide high uniform strength in all directions, including high temperature alloys such as ASTM A 297, and high impact/abrasion alloys such as ASTM A 532 Chrome White Iron and ASTM A 128 Manganese.


The main function of ball mill liner is to protect the ball mill main parts free from abrasion, the most important requirement for the material is the feature of good wear-resistance and high toughness. The material high manganese steel with enough toughness, and it will become cold-hardening with some extent impact, that will make the material better on hardness and wear-resistance, so it is used as the widely used material for liners.


We have the advantages:

- Chinese competitive cost

- German hi-technology

- Belgian quality
