19、 bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental

20、 and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directive

21、s, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies ca

22、sting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 1927-1 was prepared by Technical Committee ISO/TC 33, Refractories.ISO 1927-1 cancels

23、 and replaces ISO 1927:1984, which has been technically revised. ISO 1927 consists of the following parts, under the general title Monolithic (unshaped) refractory products : Part 1: Introduction and classification Part 2: Sampling for testing Part 3: Characterization as received Part 4: Determinati

24、on of consistency of castables Part 5: Preparation and treatment of test pieces Part 6: Measurement of physical properties Part 7: Tests on pre-formed shapes Part 8: Determination of complementary propertiesiv ISO 2012 All rights reservedBS EN ISO 1927-1:2012ISO 1927-1:2012(E)IntroductionThe general

25、 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 control;b) checking the conformity of the delivery as compared with claimed properties;c) the control of ba

26、tch 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 conditions (target date, location). Quality control and final control of lining should not be considered in th

27、e 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 linings are generally not fired, so that the high temperatures which result from use create firing which

28、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 level of maximum temperature reached on the hot face directly depends on the working temperature of the

29、 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.

40、ixing with water or another liquid. They are placed by casting 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 cast

42、ded into the four categories given in Table 1.NOTE If significant 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

According 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 m

49、echanical) or vibration. They harden under the action of heat above ambient temperature.4.3.2 Plastic refractory materialsThese are materials that are coherent and ready for use, with a plastic consistency, made up of refractory aggregates, bond(s) and liquid(s). According to the type of product, the main bond may be ceramic, chemical (inorganic or organic-inorganic) or organic.The materials are supplied in soft, pre-formed blocks or slices and placed by ramming (manual or mechanical).
