EN ISO 1927-1:2012 (E) DIN EN ISO 1927-1:2012-11 3 IntroductionThe general objective of this part of ISO 1927 is to define, with as much accuracy as possible, the control of monolithic (unshaped) refractory products with special reference to the following:a) quality con

25、trol;b) checking the conformity of the delivery as compared with claimed properties;c) the control of batch homogeneity;d) the final control of linings.Properties are unavoidably influenced by industrial placing as a result of the equipment, environmental conditions and often by specific site condit

26、ions (target date, location). Quality control and final control of lining should not be considered in the same documents, since the former requires accuracy and clean operative methods while the latter requires the control of the placing.Monolithic (unshaped) refractory products used in industrial l

27、inings are generally not fired, so that the high temperatures which result from use create firing which results from use creates complicated conditions that make control difficult. The main points to be mentioned are:1) the temperature gradient, the consequence of which is a property gradient;2) the

28、 level of maximum temperature reached on the hot face directly depends on the working temperature of the equipment;3) the life of the equipment may be numbered in hours or in years.NOTE Properties measured in the laboratory frequently do not reflect the properties of the material when installed.EN I

32、nds, prepared ready for use either directly in the condition in which they are supplied or after the addition of one or more suitable liquidsNOTE 1 They can contain metallic, organic or ceramic fibre material.NOTE 2 These mixtures are either dense or insulating. Insulating mixtures are those whose t

35、chemical bond (inorganic or organic-inorganic) with hardening by chemical, but not hydraulic, reaction at ambient temperature or at a temperature lower than that of a ceramic bond, or an organic bond with binding or hardening at ambient temperature or at higher temperatures.EN ISO 1927-1:2012 (E) DI

They are placed by casti

39、ng with vibration, by casting without vibration (self-flowing), by rodding, by shotcreting or when necessary by tamping. The bond is formed and hardening takes place without heating.4.1.2 Regular castableHydraulically bonded refractory castable containing cement but without deflocculant.4.1.3 Defloc

40、culated castableHydraulically bonded refractory castable containing cement or other hydraulic binder, a minimum of 2 % by mass of ultra-fine particles (less than one micron) and at least one deflocculating agent.This type is in turn subdivided into the four categories given in Table 1.NOTE If signif

41、icant lime content is introduced by other raw materials, this may be marked in the data sheet separately and has to be neglected when the type of deflocculated castable is defined.Table 1 Categories of deflocculated castableCategory Content (%) CaOMin MaxMedium cement castable (MCC) 2,5 -Low cement

44、e 4.1) (dense or insulating) which is supplied dry and used after the addition of water during or before gunning;b) a ceramic bond mix (see 4.3.2) which is especially designed for gunning under high air pressure with special equipment, and is normally delivered in a ready-to-use state;c) a chemical

45、bond (inorganic or organic-inorganic) with hardening by a chemical, but not hydraulic, reaction at ambient temperature or at a temperature lower than that of a ceramic bond;d) an organic bond with binding or hardening at ambient temperature or at higher temperatures.According to the type of bond, a

46、further distinction is made between hydraulically bonded, chemically bonded and ceramic bonded gunning materials.4.3 Refractory ramming materials4.3.1 Refractory ramming mixesThese are materials that are non-coherent before use, made up of refractory aggregates, bond(s) and if necessary liquid(s). A

47、ccording to the type of product, the main bond may be ceramic, chemical (inorganic or organic-inorganic) or organic.The materials are used as delivered or after the addition of liquid(s) and placed by ramming (manual or mechanical) or vibration. They harden under the action of heat above ambient tem
