Features of cast steel balls include:
1. High hardness: Cast steel balls have a high hardness, usually in the range of 60-65 HRC, which makes them have strong wear resistance when grinding materials.
2. Good impact resistance: Cast steel balls have good impact resistance and can withstand large impact forces without rupture or deformation.
3. High wear resistance: The Cast Steel Ball has high wear resistance and can maintain its shape and surface quality for a long time in the process of grinding materials, reducing wear and damage.
4. Uniform hardness distribution: The hardness distribution of the cast steel ball is relatively uniform, which can provide a more stable grinding effect and reduce the phenomenon of over-grinding and under-grinding of the material.
5. Good corrosion resistance: Cast steel balls are usually made of high-alloy steel materials, which have good corrosion resistance and can be used for a long time in humid and corrosive environments.
6. Wide applicability: Cast steel balls can be used in various grinding equipment and processes, such as ore mills, cement mills, ball mills, etc., suitable for grinding materials with different hardness and properties.
7. Simple production process: The production process of casting steel balls is relatively simple, the cost is low, and it can meet the needs of large-scale production.
In general, the cast steel ball has the characteristics of high hardness, good impact resistance, high wear resistance, uniform hardness distribution, good corrosion resistance and wide applicability, and is widely used in the grinding process of mining, cement, building materials and other industrial fields

Door and window cover construction process
1. Check the selection of the base material for wood keel and 15mm blockboard or MDF for the base material. Before the construction, check the error of the flatness of the base wall exceeds 30mm. Use the corresponding measures. After the wall is well damaged, apply the cement mortar to make up the leveling and then make the surface finish.
2, the door and window cover grass base board block material laying base with a dry wood hit the wooden wedge fixed 5mm from the ground to prevent flooding. The use of white latex on the cover plate and nails to fix the white latex should be used to brush the plate.
3. The thickness of the door leaf is generally about 38mm. The specially reinforced wood board at the lock can be cross-opened to prevent deformation.
4. Installation of door and window sash: The distance between the door and the window (surface height) is 5-8mm, and the left and right upper door gap is 2-3mm. The door leaf is combined with the door and the tight gap is less than or equal to 2mm. The hinge position is 1/10 of the standing height. Door-moving fans involving frosted glass should be played in the smooth part of the glazed glass after the appropriate amount of glass glue protection glass kitchen and bathroom matte surface should be outside the junction where the matte surface should be inward.
5. The installation hinge must be double-sided on the door leaf and the door frame. The opening and hinge of the door leaf are tight.
6. The height of the door lock from the ground 900-1000mm (the center of the lock) The position of the lock hole The gap between the correct lock tongue and the door leaf lock and the door frame should be tight. After the lock is installed, it must be bandaged to prevent contamination.

7. Sliding door: Use the small slide rail within 1500mm of the door and window sash; use medium 1500-2000mm; use large slide rail above 2000mm. When determining the width of the double-leaf double-track sliding door leaf, the overlapping edges of the two doors should be more than 10mm. Horizontal and vertical joints should be uniform, tight, hidden sliding doors should be closed after the door is installed and qualified.
8. During the construction, special attention should be paid to the treatment of the upper part of the door cover and the upper and lower side of the door leaf.
9. When the spring door is installed, the door should be drilled and the door should be drilled. The shaft should be opened on the ground. The upper and lower axis of the spring should be on the same vertical line. The spring should be buried flush with the ground. Fine concrete should be used for irrigation. Both sides of the spring rocker fan and the door fan should be tightened.
10, door cover base plate with the plate does not allow horizontal use of longitudinal 2-3 with the entire board to leave 2-3mm stitching so as to prevent deformation of the grassroots.
Door and window cover construction notes
1, according to the requirements of the room and drawings made curtains box, if you do not directly install the curtain rod curtain box, in the installation of curtain rods, you should pay attention to the window frame and the length of the curtain rod thickness and length.
2. When making a panel curtain box, first make a 7-shaped frame pinned to the top, and both sides should be sealed with wood panels. The vertical border under the application of a 20 * 18mm wooden bar reinforcement, nailing, to prevent deformation, such as the re-sealed nails decorated with water, do mixed water paint must ensure that the grass-roots surface smooth.
3. When the window cover is made of block board or density board, the base board should be fixed on the keel of the window frame base and then nailed. The "zigzag" shaped nail prevents the curling of the line, the included angle should be dense and smooth, and the window cover The next mouth should use marble, so as to avoid deformation due to moisture.
4, the door cover should be made of wood frame, planing, planing straight, and then in the assembly molding installed on the wall, covering the base board and veneer.
Door and window cover acceptance criteria
1. The door cover shall be vertical, the veneer shall be smooth and square, and there shall be no large or small head or bell mouth; 2. The cutting angle of the wooden door and window cover is neat, the joints are tight, the surface is smooth, there is no planing and burr. 
Door and window cover base layer construction process, attention to doors and windows set up to protect the wall side of the function, the door and window cover can be connected to the interior decoration materials, but also has a very good decorative effect. The base layer of the door and window cover is closely related to the quality of doors and windows. Therefore, it is very careful and promptly accepted during construction. However, ordinary owners do not understand the knowledge of the construction of the door and window cover base layer, but it does not matter. This site has collected comprehensive construction process flow, precautions and acceptance criteria for the owners.
